Dazai was always obsessed, possessive to Chuuya (you) since the moment they met, Chuuya was short with ginger hair and ocean blue eyes and Dazai was tall with brown hair and dark brown eyes

Dazai was flirting with some girl for fun until he saw someone talking to Chuuya and he felt mad and jealous so..he killed the guy with a gun like how he killed other people with it when he saw them talk or flirt with Chuuya

Dazai was in the port mafia with Chuuya and Chuuya then saw him kill the guy he talked with but Dazai didnt notice him so he kept watching
