It’s actually sadder than I thought. So Tadano isn’t completely blind to romantic attraction, because he can notice one between two other people. But he’s still very dense when it comes to attraction to him.
Does he think that he doesn’t deserve romance? :(
Well, my parents’ friends are married with the same age difference as protagonists (husband was 21 and wife was 33 at the time), so protags’ marriage doesn’t look completely impossible.
Just saying
