I thought there was a bigger age gap between them. They're only 5 years apart

It really pisses me off when i read shit like this. How stupid can someone be, firstly he knows the body he's in is weak. then he turns off his phone. After you heard what the guy said at the entrance you still follow him? At this point i really dont even care if he dies. Useless. I was so looking forwards to an update... ¬_¬
I don't think he's 100% registered that he's in a weak body. He called that guy a murderer. He was talking as if he were his true self. He has at least one person who acknowledges who he really is, and he keeps is old self alive in his personality. It's an unthinkable situation, so a normal thought process isn't necessarily expected for Tae Min. In general he's not thinking properly. He's looking at things from a third person's POV. He doesn't realize that he's in the body of the kid who was beaten and raped. Idk if that makes any sense, lol.
I would agree with you, if it wasn't for the fact that he has mentioned/acknowledge the weakness of the body he is in, quite a few times.(and somehow STILL hasn't done anything to improve it, like so much free time to join a gym) He literally puts himself in these situations thinking that his smart mouth will make his opponent think twice about who they're messing with.
But he forgets that, the old him could backup his words/confidence.
Why did the quality get so shit??
It's because the mangaka hurts her hand and had to draw using left hand...
