in the case of chapter 1, it was more he did it so she wouldn't get blamed for the engagement break (he didn't know she liked him like he liked her), he did it because he thought she wanted to be a scholar and didn't want to limit her... but obviously he's dumb because it would have been solved with *communication*

Volume 5 chapter 1 and 3 sucks!!!
I hate these kinds of stories where the guy break up with the girl and pretends to be with someone else just to see the girl suffering and jealous( ̄へ ̄); This is not romance, it's just manipulation!!!
