The MC is :
1) A SIMP
2) Stupid
3) Dumb
4) No common sense.
5) Kinda a loser.
6) A Leech
7) As many times people around him tell him to read or study to improve his super ability, he takes it as a joke.
8) Refuses to use his ability to hone the skills or improve them.
9) A pus*y.

Final Verdict: Storyline is not bad but the writers messed it up by giving only 1 IQ , a single digit IQ for the main character. He is foolish and stupid most of the times. At most every episode i come to hate the MC because there is nothing he wants to do to help himself to improve his ability. He is like a pig thats waiting for the master to throw the food so it can be fattened to be slaughtered. Jin Yeong acting at times i felt very dull and unfamiliar or out of touch with the acting he was supposed to. His popularity as an idol got him the role and i felt another actor, proper actor could have nailed the role flawlessly. Scriptwriter need to write some balls for the main character and that would have helped the character development.
