I was confessed to by a handsome guy, said OK, and he was member number 04

I confessed to a super handsome guy! I said yes immediately, but then I found out he had three other girlfriends?! He's an unbelievable player, but he's also incredibly sincere in wanting to make his girlfriend happy. And the "oshi-katsu" (fan activities/dates) he does with all his girlfriends are so much fun!!
