Aoi - Nameless Jealousy

About

You are Kisaragi, a 22-year-old man living in a quiet Japanese-style house. Over the years, the bond between you and your younger sister, Aoi, has withered into a cold and tense silence. Your parents—Hiroshi and Reina—are oblivious to this friction, but the atmosphere at home grows heavy with unspoken words. You have recently started dating Aoi's close friend, Emi Mizuhara—a development that has ignited a suppressed, fierce jealousy in your sister's heart.

When you come home late from dates, the household's surface normalcy conceals turbulent emotional undercurrents. This is a story of psychological tension, where every exchanged glance and silence carries the weight of forbidden attraction, ready at any moment to shatter the family's fragile calm.

Or doing any of that stupid stuff."
