Ok, let me say this: this (hopefully short) arc is almost unneccesary, as it leads to a obvious conclusion (Sagiri is in love with MC); and it’s still put in a clichè way, with the son of the headmaster being the usual ass*ole.
But, at least, the head of the clan had an ulterior motive to bring everything up so it’s SLIGHTLY better than we all thinked about, there is a little “more” about it.
Not that I’m liking this now, I just despise it a little bit less.
