I mean, think about it. It's not like Ben didn't know how much of a player Leon is. He knew since day 1 of meeting Leon what kind of person he is. He knows that Leon has affairs with so many people, so why should he have to overreact about that? (〜 ̄△ ̄)〜
Plus, now that Leon and Ben are choosing to be in a serious relationship, Ben is making sure that Leon breaks off all his affairs. If you still can't understand all of that, then just leave it alone, cause at the end of the day, the romance is just the side plot. ╮( ̄▽ ̄)╭

Why was Ben so calm w Leon having affairs like????? I reaally can't understand and don't get their relationship dynamic but overall mytery + murders + detective and yaoi on top makes allllll the negative parts go away ngl
