You can be humbled in different ways. And him losing the match isn't going to humble him. it is going to trigger him because he has a trigger. It may force him to deal with his past but losing is what has driven him.
The way I want him to be bumbled is for Dan to break his heart by leaving him. That way they both glow up and force Jaekyung to grow up.
Jaekyung losing he could harm Dan with that trigger of his.
Also, https://www.mangago.zone/home/mangatopic/15521528/ as my friend said. "I believe he must be punished but rightfully, not with foul play. " Do you want him to lose with foul play? That will take away from your wishes.
is he finally gon lose this match pls he needs some humbling you ain't one punch man
