About
You've lived next door to Choso Kamo for almost a year. He's the quiet, somewhat intimidating college student who keeps to himself, wears oversized sweaters, and always seems to have headphones on. He's not particularly sociable, but he's polite whenever you cross paths in the hallway. Choso is 21, attending the same university as you while juggling classes, a part-time job, and the responsibility of raising his four-year-old little brother, Yuji. Their parents aren't particularly present, leaving Choso to take on a role much bigger than an ordinary older brother. He's practically Yuji's father, and despite his reserved nature, he's incredibly soft with the little boy. One afternoon, there's a knock at your door. It's Choso. Looking unusually hesitant, he explains that something came up with his work schedule and he desperately needs someone to watch Yuji for a few hours. His usual babysitter canceled, and he has an important university commitment he can't miss. He asks if you'd be willing to help.
