Living together with your cute junior

Story Overview

You’re not exactly your average office worker — about a year ago, your house burned down, leaving you without a place to stay.

After some rough luck, you manage to find a shared rental that you can move into immediately. But on the day you arrive, surprise — your roommate turns out to be a girl… and not just any girl, but your cute college junior, Aoi.

Sure, you know each other, but living under the same roof as a guy and a girl is still kinda awkward. You both immediately complain to the rental management company, only to be told everything is strictly by contract — and backing out would mean paying a hefty penalty.

That classic rom-com “lucky perv” moment you just *have* to include

With no real way out, the two of you agree to just give cohabitation a shot for a while. Luckily, both of you are busy with work, so you barely run into each other at home. For a time, things stay pretty chill.

But that balance doesn’t last long. Out of nowhere, your company announces a switch to full remote work starting immediately. As you drag your work gear back home, you realize… Aoi’s in the exact same situation.

Which means that fragile peace? Yeah, it’s about to get shaken up.

So what kind of moments will come out of this love-hate, sweet co-living situation?

Game Objective

Living together naturally leads to all sorts of interactions — and friction. The goal here is to build your relationship with the heroine through daily conversations and interactions.

You’ll go from simple roommates, to friends, to something more… and eventually lovers. It’s all about enjoying that slow-burn, sugar-sweet cohabitation life with Aoi.

Early on, she won’t hold back with those cold stares

But once you get closer, she’ll even start going along with some of your more “spicy” requests

Gameplay Loop

The game runs on a day-cycle system, with each day going from 6:00 AM to midnight. Since you’re working remotely, you’ll mostly be at home, and the heroine follows a fairly fixed schedule — doing the same things at the same times each day.

Your job is to find opportunities to talk and interact with her during daily life, triggering different scenes and conversations across various situations in your shared living environment.

There’s no time limit, so you can take it easy and explore different scenarios at your own pace. No pressure — just vibe and see where things go.

UI & Core Gameplay Breakdown

Since everything in this game is menu-driven, the controls and overall gameplay loop are pretty straightforward. You’ll basically be moving around, handling daily tasks, interacting with the heroine, and repeating that cycle.

Let’s break down the UI, stats, and a few things to keep in mind.

Main daily UI

First up is the main daily interface. Starting from the top:

• Top-left shows the heroine’s status panel
• Top-right displays the date, time, and your current objective

At first glance, the heroine’s status panel looks super minimal — and yeah, it kinda is. That’s because most of the values are hidden. But don’t worry, only a few stats actually matter. Here’s the quick rundown:

1. Relationship: Progresses through four stages — Roommates, Friends, More-than-friends, and Lovers. Each stage unlocks different events and interactions. This increases alongside intimacy.
2. Affection (Intimacy): The most important stat in the game. All story progression ties into this. The good news? It only goes up, never down. You build it through daily interactions.
3. Trust: A bit of a weird one. If it drops to zero, it’s game over. But outside of that, it barely matters. After becoming lovers, even hitting zero doesn’t really do anything. It goes up or down depending on your actions.
4. Location: Tells you where the heroine is or what she’s currently doing.

Of course you’ve gotta barge in when she’s changing, right?

Next are the hidden stats. These aren’t shown as numbers, but instead appear as icons beneath the status panel:

5. Mood: Basically her emotional state. This is the second most important stat because good mood = faster affection gains. Keep her happy whenever possible through interactions and gifts.
6. Hunger: If she’s hungry, her mood drops. She can cook for herself, but feeding her boosts affection.
7. Cleanliness: Supposedly, low cleanliness can make her sick, but she bathes on her own and it’s rare to actually see this become an issue. Might be tied to specific conditions.
8. Bladder: When it fills up, she’ll go to the bathroom — and yes, there are related events.
9. Arousal: When maxed out, she’ll head back to her room to relieve herself. Again, there are events tied to this.
10. Sleep: If she’s sleepy, her work efficiency drops — though this doesn’t really impact the player much. Not clear if it triggers anything special.

The best way to keep her in a good mood: gifts, gifts, and more gifts

Out of all the hidden stats, Mood is by far the most important, since it heavily affects how quickly you build affection. If you’re aiming for faster progression, keep a close eye on it.

Now for the top-right section:

The date itself doesn’t really matter — what matters is the time system. The day is split into three main periods: morning, afternoon, and evening, each lasting 6 hours.

Time progresses as you play, and most actions consume about 0.5 to 1 hour. Some actions like working or resting will skip an entire time block.

As mentioned earlier, the heroine follows a mostly fixed daily routine. However, you can still interact with her using the “Call” function, so her exact location usually isn’t a big deal — except during certain moments when she simply won’t respond.

Calling her over depends on timing — otherwise she’ll just brush you off

Next is the bottom command bar.

Aside from the usual Stamina and Money, the commands from left to right are:

• Rest
• Shopping
• Cooking
• Cleaning
• Laundry
• Bath
• Exercise
• Work
• Items
• Shop

On the far right, there’s also a shortcut menu for switching between different locations.

Here’s a quick breakdown:

1. Rest: Restores stamina but skips an entire time period
2. Shopping: Buy ingredients (used for cooking and making coffee)
3. Cooking: Prepare meals to restore hunger
4. Cleaning: Yep… just cleaning the house
5. Laundry: Wash clothes — after buying a washing machine, you can do it together with the heroine
6. Bath: Increases cleanliness; low cleanliness can affect trust
7. Exercise: Grants a temporary “good condition” buff; maintaining it for a full day increases your max stamina
8. Work: Earn money, but skips an entire time period
9. Items & Shop: Spend money on useful items — more on this later in the guide

This might look like a lot at first, but honestly, it’s pretty simple in practice. Just follow one rule:

“Whatever stat is about to bottom out, that’s what you should deal with.”

While different actions may trigger small bits of dialogue or flavor scenes with the heroine, they don’t seem to directly affect stats much. Also, you can’t initiate most interactions with her through this menu — think of it more like a quick-access toolbar.

You’re not going on a supermarket date with her using just the shortcut menu

Now onto the real core gameplay — everything outside the shortcut menu.

The game uses fully 3D-modeled environments. While you can’t freely walk around, many objects in each scene are interactable.

Most objects give you two options:

• 移動する: Your character approaches the object and unlocks possible actions
• 調べる: Just displays a description of the object

The key lies in what you can do after selecting “移動する”

If an object allows interaction with the heroine, you’ll see a “呼ぶ” option. If she’s available, you can summon her over and trigger interactions.

What you’ll be doing most: cook a meal, call her over to eat — easy affection gains

The heroine is designed to be cheerful, playful, and a bit of a goof, which opens up a ton of situational interactions. The devs clearly put a lot of effort here — there’s a surprising amount of dialogue variety, with different responses based on your choices and relationship progress. As your bond deepens, interactions get noticeably sweeter.

This cheeky little devil junior never misses a chance to tease the MC

For example:

Early in the game, if you try to barge in while she’s bathing or changing, she’ll yell at you and kick you out. Do it too often, and she’ll actually get mad.

But later on? As your relationship improves, you can casually enter her room and even flop onto her bed. If she catches you, she’ll just sigh and go, “Seriously?” — more amused than angry. She won’t even bother kicking you out when changing.

Locker room eye candy — getting kicked out early on is basically guaranteed

Later on, you can even lie on her bed and watch her change without getting kicked out

Another example:

At first, you can’t interrupt her while she’s working. Even if you call her, she’ll tell you to wait. But once your relationship progresses, you can start pestering her until she gives in — and eventually, interactions get way more intimate.

In the kitchen, what starts as simple teamwork evolves into something closer to a married couple vibe once you become lovers. You’ll taste-test dishes together, flirt, and she might even roleplay as a newlywed wife welcoming her husband home. You can also share baths together — basically, the game leans hard into sweet couple moments.

Personally, I didn’t start seeing repeated dialogue until pretty late into the game. If you enjoy slice-of-life interactions, this part is definitely something to look forward to.

Finally, let’s talk about the “night raid” feature — a staple in cohabitation-style games.

This mode unlocks automatically after reaching a certain point in the story. Here’s a quick overview:

Night raid main interface

• The top shows a time bar — once it runs out, the scene ends
• Top-left shows pleasure and sleep meters
  
  • If sleep hits zero, she wakes up, gets angry, and your trust drops (this restriction is removed after becoming lovers)
• On the right side are action commands
  
  • Aside from undressing, you can choose to use hands, tongue, or other methods to interact
  • Move the cursor over different body parts to trigger interactions, then click to execute
• Bottom-left shows control tips (like auto mode or camera movement)
• Bottom-right lets you end the scene

If you complete a night raid without waking her up, you’ll get a level-up screen with three upgrade options:

1. テクニック: Makes it easier for her to climax
2. プレータイム: Extends the time limit
3. ステルス: Makes it harder for her to wake up

Honestly, there aren’t that many mechanics to play around with

That said… here’s the honest take:

This system feels a bit awkward. The gameplay and content here are pretty repetitive, and it doesn’t really impact the story. It ends up feeling kinda optional.

Personally, I started skipping it entirely in the mid-to-late game. If this feature is a big deal for you, you might want to keep that in mind before jumping in.

Walkthrough & Tips

Since this game follows a completely linear, sugar-sweet storyline with no branching paths, and it’s actually pretty hard to hit a Game Over via Trust dropping to zero, this section focuses more on system mechanics and easily missed details rather than “routes.”

Save System

Let’s start with the big one:

There is no manual save system in this game.

The only saving happens automatically at the end of each day. There are no save slots, which means you can’t choose when to reload.

Also, if you close the game before the day ends, all progress from that day is lost — so be careful.

Dialogue Choices with the Heroine

This is honestly one of the best parts of the game.

As mentioned earlier, the heroine’s personality makes the dialogue really fun and engaging, with plenty of moments that highlight her charm. Some choices might lower her mood or affection, but honestly, just pick whatever feels right to you.

It doesn’t affect the main story anyway — and her reactions are half the fun.

Messing with the heroine is way more fun than it should be

Raising Affection

All main story progression is tied to Affection. You’ll need to hit certain thresholds to trigger events and move to the next stage.

The good news is that tons of actions — commands, interactions, even conversations — will increase it, so you won’t get stuck.

That said, always try to keep her Mood high (you’ll see it as an icon). The difference is huge — the same action can give 2–3x more affection depending on whether she’s in a good mood or not.

Once you hit certain story points, things start getting a bit more “spicy”

Shop Recommendations

The shop mostly sells items that boost stats or improve efficiency — there’s nothing that unlocks new gameplay systems or key story events.

Recommended priorities:

• “すごいマウス” & “すごいキーボード” → Boost work efficiency (and you’ll always need money)
• “ポヨポヨプリングッズ” → Great for restoring her mood; perfect as gifts when she’s feeling down

Everything else is optional based on your preference.

Also, buying new furniture or pricier items will trigger small dialogue scenes with the heroine. If you’ve got time, it’s worth grabbing everything just to see those interactions.

Solo vs. Joint Tasks

For activities like cleaning, shopping, laundry, or cooking, you can call the heroine over and choose a “Do it together” option.

The difference:

• Solo → Increases Trust
• Together → Increases Affection

Other than that, stamina cost and efficiency are pretty similar.

About Trust

As mentioned earlier, hitting zero Trust results in a Game Over — but under normal play, it’s actually pretty hard to get there.

The main ways to lower it are:

• Peeking (being a creep, basically)
• Neglecting hygiene
• Picking particularly off-putting dialogue options

If you really want to see what happens at zero Trust, here’s a “fast track” method:

When the heroine goes to the bathroom, open the door, close it, then open it again — and repeat.

It seems like this interaction wasn’t fully restricted, so you can tank Trust pretty quickly this way.

You can actually spam opening and closing doors — and yeah, it’s kinda hilarious

Bathroom Events

Since we’re on that topic — the heroine doesn’t have a fixed bathroom schedule. She only goes when her bladder meter is full.

You can increase it by giving her tea from the shop, but it’s expensive and inefficient.

A better method:

There’s a coffee pot on the kitchen table. You can use ingredients to brew coffee, which becomes an item you can gift. It increases her bladder stat more than tea — and it’s basically free.

If you’re trying to trigger bathroom-related events, this is the way to go.

Unlocking Her Room

This isn’t clearly explained in-game, so here’s the deal:

Sometimes the heroine locks her door. If you try to peek, the game hints that you can unlock it with a coin — but doesn’t tell you where to get one.

The coin is actually in the wallet on your desk in your room. However, it only becomes obtainable after reaching a certain point in the story.

Hidden Events

While all main story content is tied to Affection, there are also hidden events with no clear trigger conditions.

Examples include:

• Going to the gym together
• The heroine roleplaying as your boss

These don’t appear in the gallery, and their triggers are unclear — they tend to happen randomly while experimenting.

One of the hidden events: glasses-wearing junior doing a “hot boss” roleplay

One hidden event the author did figure out involves the bathroom:

Call the heroine to a spot slightly away from the bathroom, then keep giving her drinks until the bladder icon appears. She’ll then rush to the bathroom.

At that point, exit the interaction, quickly move to the bathroom via the shortcut menu, and just wait there without moving.

You’ll end up awkwardly locking eyes with her outside the door — and after a while, a special event triggers.

Tried it just for fun… didn’t expect it to actually trigger a special scene

The rest? You’ll have to discover on your own.

Final Thoughts

This is one of the more popular recent titles on DLsite, and going in, I was a bit worried about performance since everything — characters and environments — is fully 3D.

But overall, the experience was surprisingly smooth. There are a few bugs here and there, but nothing that really disrupts gameplay. The heroine’s model is also pretty cute.

The 3D models are solid enough, in my opinion

What really stood out, though, is the writing.

I’ve previously played another cohabitation romance title, 秘密のシェアハウスせいかつ, where the heroine had a more innocent, naive personality as a student, and her dialogue reflected that.

In contrast, this game’s heroine feels more like a playful, slightly teasing “little devil” junior — and since the characters already know each other, the range of conversations feels broader and more natural.

The dev team clearly put effort into making her reactions dynamic — she responds differently depending on your choices, throws in playful banter, and every single line is fully voiced, which adds a lot to the presentation.

That probably also explains the slightly higher price point.

Some of the writing just randomly hits that perfect comedic timing

That said, the H-content feels a bit lacking in comparison.

Outside of story-driven scenes, once you unlock free intimacy after becoming lovers, it seems like there are lots of locations to choose from — but in practice, they’re pretty similar and lack variety.

That’s probably the biggest downside, and it’s unclear whether the devs plan to expand on it in future updates.

Main story H-scenes are decent, but the free-play side feels a bit lacking

Overall though, I had a really solid time with this one.

The back-and-forth between the main characters — sometimes playful, sometimes flirty — combined with the fun, lively dialogue, makes for a genuinely enjoyable experience.

If you’re into this kind of “bickering couple turns into lovers” pure romance vibe, or just like the heroine’s character type, definitely give できる後輩アオイちゃん！ ～二人ぐらし始まっちゃいました～a shot.
