DEFINITELY MR YUUJIN MIKOTOBA. he had a wife after all. he was sexy. he IS sexy. hes kind and soft and a doctor how could you NOT love him
then hmm id say ryuu because hes like, pretty normal? hes not like barok or sherlock or kazuma hes a guy. pretty fun to date, maybe a bit insecure but that makes him cuter

also im biased but i'd date jigoku like he might be fucked up but hes kind and beefy and like im pretty sure being a judge and a minister pays well
