About This Game

This is a romance visual novel about spending roughly 100 days

living together with two mysterious “Egg Girls”

Your daily choices affect four emotions: Affection, Empathy, Comfort, and Tension.
Drawing closer is not the only option—sometimes,

choosing to keep a little distance matters just as much.

Over time, those choices quietly shape the tone of conversations,

facial expressions, distance between characters, story events, and ultimately, the ending itself.

Even the same words can feel completely different depending on the

relationship you’ve built and the emotions of that day.

Yukino is awkward, quiet, and kind.
Rinne is cheerful, honest, and straightforward.

As you spend your days with them, watch their feelings shift little by

little—and see how your relationship changes with them.

Rather than relying on dramatic twists,

this story treasures the weight of time spent with someone,

the quiet sway of unspoken feelings,

and the lingering afterglow that remains after the ending.

This is an all-ages title.
It does not contain explicit sexual content or graphic violence.

Features

Heroines Shaped by Emotion
The balance of Affection, Empathy, Comfort, and Tension changes dialogue,

expressions, reactions, behavior, story events, and endings.

A 100-Day Cohabitation Story with Branching Routes
The game features separate routes for Yukino and Rinne, along with five endings.
The small choices you make over 100 days gradually change your

relationship and eventually lead to major turning points in the story.

Voice and Animation That Capture Subtle Emotion
Japanese voice acting and Spine 2D animation carefully express blinking,

breathing, eye movement, gestures, and the emotions hidden in the space between words.

A Gentle, Bittersweet Romantic Experience
This is a game for players who enjoy changing relationships,

emotional nuance, and the lingering feeling that remains after the story ends,

rather than intense drama or explicit content.

Estimated Play Time
Each route takes about 3–4 hours to complete.
By exploring multiple routes and endings, you can enjoy the story for even longer.
