@SRoien I perfectly understand the point of OPM, and my point is that it's a bad concept to build a story from. Solo Leveling has written itself into a corner where there are only two logical ways out:
1. JinWoo's father quite possibly has the same ability, and so he could be made an enemy who could rival JinWoo.
2. JinWoo was granted his ability in some weird twist of fate, so it could be taken away in the same manner.
Otherwise it's going to get really, really boring for anyone who expects a story to be more than a showcase of colorful artwork.
