I’m sure she has a sob story but author better not let MC forgive her when he finds out all of this, KR novels(not sure ab manwha) are usually pretty good in my experience at not forgiving just because they have a sad story or are an attractive girl, so I’m hopeful.
Still unsure of how he can end up fighting them though, he needs them in a way, and their overall power must be crazy.
Also, I wonder if the reason she’s trying to control his level is to keep him within control? Or is it because she wants him to win some kind of “rookie reward” or tournament (like maybe lvl15 or under request solving?) maybe those are stretches but that’s the only thing I can think of.
