Honestly I liked it. It's nice to see an author (or mangaka here) who's known to write stories (or draw/script manga) with positive vibes and then suddenly write (or draw/script) something with lots of drama, and less positive vibes along with different kinds of character types that you wouldn't think they would write about. It really shows that they have more talent than you think.
I bet that if there was a different kind of art style, and a less popular mangaka making this I would have thought differently.
