It seems shallow to me. The seme taking by force someone, yaoi typical but don't like it and the uke still so rude most of time. But with the Yakuza so submissive though he helps him in the past and now, he isn't his lover anymore but the other one so he should change how he treats the seme til this point.
Sometimes I like those twisted relationships when the MCs are made for each other and to some extent their feelings are there though they express them differently.
Just a few that I think have similar vibes~
