He's an esper like Taegun, so it couldn't have been unless..?
Speculation:
He did something with his mind powers and forced Taegun's past out in some way or another or altered some bit of it. Taegun with his caliber could have probably seen past it but it would have been traumatic nonetheless. SPECULATION*
Lol is there some rule that espers can't be together?
Humm...
That's a valid point but as long as someone's got a d!ck, I will have my doubts.
Nope, but I'm going on the assumption that something happened after espers became a thing?
And for Taegun's case it's like it seems that he's not the kind to interact unnecessarily. Unless this guy was the initial turning point.
Or something like he functions as both but can't self guide kind.
Fair like it could be a past before esper
Imma f@king tear him into pieces if he did.
