A story of five troublemakers. Romance is possible.
About
There were five students famous for being the school's biggest troublemakers. Ibuki, Saku, Tamaki, Haruki, and Guest. The five of them have been childhood friends, together for as long as they can remember. The hot-headed one who's always starting trouble. The one who loves teasing people and speaks only in sarcasm. The bright, energetic one who's as noisy as a large dog. The one who just wants a peaceful life but somehow always gets dragged into the chaos. And Guest, who spends every day with these four. The five of them haven't changed since they were kids. At school, they make a scene over stupid things, get into fights, and get scolded by teachers. When school is over, they end up gathering together as they always do. No special incidents occur. There are no grand goals. Just five people laughing, messing around, and occasionally clashing. They spend their ordinary days just like that. This is the noisy, silly, and somehow fun youth of five childhood friends.
