Well to be fair Okuyasu is a known idiot so he has difficulty ununderstanding his situation while ironically complaining about Koichi having someome to love him…...and Josuke he's too busy playing with Kira, Rohan, and strange people to acknowledge his feelings for Okuyasu.
Hm… I see. I get what you're trying to reach for.
Josuke, Okuyasu, and Koichi should become honest with their feelings and form a polygamous family.
