I agree, how on earth is Midnight allowed to teach?
Also, Endeavor is the third worst dad in anime (becoming a better person later on is not becoming a better dad), after Gambino (#1) and Shou Tucker (#2)
edit: s1 Sung Jinwoo does have some stakes, but his growth is too fast, with less than 20 episodes for him to progress from the weakest in the verse to the strongest. S2 Sung Jinwoo is the same as I originally said.
My problem is that he gets too strong, too fast, with no real stakes because he just keeps winning. He very quickly turns into the strongest in the verse and it doesn't FEEL earned.
