Wow, that tutor pisses me off so much.
Not just what he did to Meguro but how nonchalant he is about it. He doesn't even see what he's done to begin with. He literally used Meguro to burn some time and then walked away when he didn't have any legitimate reason to stay with her. It's not that he purposefully played around with her heart just to break it but he naturally believes that if it's too much trouble or inconvenient for himself, it's fine to break their relationship without caring for what the other person thinks. It's as if he never learned basic human socialization skills and learned only to care for himself.
If there is a confrontation between the MC and the ex-tutor, I hope that the author doesn't brush it off with something heart-warming like, "Oh, I understand that you only care for yourself but Meguro is different now, please walk away." I hope that the tutor gets FUCKED UP. Like, majorly. Idk,
I've never been so annoyed at a manga character before in my life to write this much and I feel like, with the mood of this story, there's not going to be enough consequence for the tutor for his mental attitude.
