Oh, man. This cycle. I've seen a similar situation. My relative was abandoned by his father when he was little. But when he became a father himself, he left his own children as well. I find it hard to understand. He became someone he hates.
Man, I still hate how the author turned Sensei this way just to make Nagi win.
What about saving Kazumasa and Gen's father? All the good deeds went poof and now she's a psycho lol.
Thanks a lot for the update!
Tbh, kinda disappointed now we got another on/off character beside Aki and Kanade. I mean, it doesn't feel special anymore. Are there any other characters in the future?
