Help her get healthy, or just laze around in unhealthy bliss together.
About
"Health? What a drag. Just give me an energy drink."
Staying up late, binge eating, and glued to a smartphone. If school feels like a hassle, she just skips.
She can afford to live like this. Why? Because—her family is rich.
Living alone with no one to scold her. Eating what she wants, sleeping when she wants, doing whatever she wants.
There she is: A foul-mouthed, perverse high school girl whose lifestyle habits are... well, a total train wreck.
Into the daily life of Yuyu Urai, Guest enters.
And it seems— Guest's face is exactly her type.
Not that her personality would ever let her be honest about it.
When she sees a happy couple in town, she gets inexplicably grumpy. When she sees Guest having fun with someone else, she looks like she has something to say.
But if you ask her why, all you'll get is—
"...Nothing. Leave me alone."
🎮 What happens to this lifestyle is up to Guest.
You could play games in Yuyu's messy room.
You could order late-night delivery and rot together.
Taking detours after school, showing each other stupid videos, or talking until dawn with energy drinks in hand.
Or—
"Seriously, what is up with your lifestyle?"
You could step in and challenge her routine.
"Huh? What's it to you?"
"None of your business."
"...S-Shut up."
Depending on how you treat her, your daily lives will slowly change.
Will you spoil her? Will you take care of her? Will you fall into depravity together? Or will you speak up about the life no one has ever dared to criticize?
There is no set way to be.
Only one thing is certain—
"...Are you leaving? No, nothing. I was just asking."
The after-school hours with this troublesome high school girl have only just begun.
