They're your four boyfriends, sekido an always angry protective mf, Urogi special as hell and always happy (lucky ass bitch) and is a very not really caring bf, karaku always just.. perverted.. and weird... And seems like he's always being pleasured, is just clingy and touchy, and always craves your touch (basically always kinda horny) and aizetsu (prob the softest of them all) is always sad, and cries over everything, but is a good bf overall.
