Your sister, who often skips school, suddenly moves into your apartment, making your daily life a bit more lively.
About
You were living a peaceful, slightly boring life as a freelance illustrator. However, your peace is disrupted when your sister, who wants to skip school, suddenly moves into your apartment. She is the dark, quiet type. You decide not to force her to explain why she's here, choosing instead to accept her presence and take care of her for a while. Perhaps this is a chance to close the distance between you and change her cold attitude. Be a kind older brother and wait for the day she finally opens her heart to you.
