After learning he can transfer his consciousness between the two, he becomes optimistic and believes to can finally start over at his new school.

Good, but I don't think the show made all the right decisions.

As I saw the Netflix trailer play out, I wondered if this was going to be another Bagel Girl. It had few similarities, but better production and didn't throw an odd twist at me at the end. Not yet. Looks like they're planning another season.

Our main character is unpleasant and it's not until he changes his appearance he becomes likeable. That's not because of my "lookism", mind you, the real Hyung-Seok simply is a whiny, entitled bitch, which is somewhat acknowledged later on the series, but none of this changes that the character wasn't written in a way that invites you to sympathize with him.
He had no redeeming qualities. I thought the singing talent his mother hinted at might've been his saving grace, but it was.. truly awful. More about that later.

The series had some unexpected turns, but would also linger on certain matters for too long or not long enough. There were many characters that got shoved aside shortly after their potentially important introduction, and the reason why a character did or stopped doing something was rarely explained.
I initially worried Hyung-Seok was going to befriend his bullies, turning them into his comedic ride-or-die allies, and it looked like the show attempted it, but Hyung-Seok pulled a move I've rarely seen fictional bully victims do; and associated with other victims only. Of course, one of those poor fools keeps getting his shit kicked in whilst Hyung-Seok -with his super strength and speed- only watches it happen for some reason. It got old very quickly, and at the same time, the level of abuse these kids went through was otherworldly cruel. Why are there never any teachers or adults around when this happens?

The ending was a slight let-down in the sense it was the pretty Hyung-Seok who attended the stage. I thought the sore throat plot line would lead to Hyung-Seok accepting his real body and perform as his true self, since he was claimed to be such a good singer and all.. but, that was a fucking lie. And of course it is, because they gave this character the most stupid, dopey voice, like they always do with "fat loser" characters. The only real talent the normal Hyung-Seok had was his ability to see punches coming, but again, he needed his pretty self to put this talent to use.

Another point where the show greatly missed the mark is Hyung-Seok's belief his life is great as a handsome boy, as it's really not. He keeps attracting self-righteous punks who want to beat him up; how's that any different from his normal life?

I do like that the ending wasn't exactly a happy one. Perhaps needlessly cruel towards the boy who worked so hard to prove himself and looked genuinely fresh on stage, but why expect anything else from a sleazebag record manager. I accept it.
