I don’t share the same adoration others feel. Some story elements felt rushed and undercooked, particularly “Pina’s” past life. Why was she so bitchy? We know literally nothing about her.
I’m hoping he becomes a permanent fixture in the manga, and that he “beats” her this time at least. It would create an interesting dynamic not only between those two, but her and the MC as well. Maybe have the MC “step out of line” and ignore her in favor of trying to learn from him?
