So did he have any kind of ways to control them or some kind of prevention in case he got betrayed again? Surely he's not naive enough to not learn from his previous mistake right?
Even though he could revive again, he can be detained like being imprisoned, sealed, or something.
@bakauguu looking at how the author making a clutch by making the MC arrived late in Jeju Island arc, I doubt it would be that easy. Drama would come sooner or later.
The description make me remember about a "H" where the MC let his friend's mom to freeloading in his place. He got caught fapping, make love, and they got married in the end lol
Put everything aside, that teacher was truly messed up. He's so biased and even accused the MC for cheating despite no proves, tho I understand that the MC used to be bad at it, but that still doesn't justify it.
