Yea classic case of "oh he's strong cuz the story says so", but still weird considering jaeha's supposed to be mental DEFENCE. It makes sense he removes someones shield or whatever to fck them over, but all that extra stuff is just way too op imo. To the point i dont understand why he wasnt just made to be an S class, would make more sense if he's the only S rank mental ability guy and he's an evil dude cuz its hard to take him seriously as an A rank. I'm also curious now cuz the nightmare thingy seems to have evolved using mcs nightmare, so is it now an S rank mental threat? and if yes then is jaeha gonna be op against that too? if yea then what the fuck author nim xd
Also he doesnt get enough flak in the story for being the groomer he is, so really hope he gets publicly shamed in the story later on
Right! Jaeha rep (in his world) would benefit a lot being a key role defeating Nightmare. Because he just could be a big support role in this, as he already is. And fame is exactly what he wants now. He's pissed with Seo bc Seo is a hindrance in his fame and not because of Jaeha past relationships.
I def could imagine Jaeha being famous to help defeat Nightmares and boom "grooming scandal" from the S rank number 1 Hero Korean. Boom! Tallest the high, biggest the fall.
Of course, since he is a villain that won't happen, but that would make the story even more complex.

Villain is so powerful or am I fail to grasp his limitations? He can control anyone's mind he touches in due 500 days, OVER AN YEAR after touch them for the first time. And he could do this in home office/remotely for all he cares. That's a big range. So, what is preventing him to make Seo jump from his office window and make it looks like a suicide? Or tamper some esper mind to attack Seo?
What are his limits? Like, he could do it only once? Then he need to touch the target again? That's why he couldn't do anything after he fails in nightmare dungeon? Or he needs to be in X meters from the target? Because neither his brother or father touch him when they were scolding him for mess with guild animals. I guess Kang family know how to deal with him?
Until last chapter, his anklet wasn't even a threat to his activities since he used to mess with Taegun and still mess with other boys. And they have zero proves for his crimes, not a single footage. Kang even said that hiding his real powers from guild/government wasn't a big deal for him.
