I agree with all of you, at first I thought too that this manhwa was gonna be similar to other manhwa, where the story begins with the main character being a complete loser and being obsessed with the strongerst/famous person. Then finds out that their obsession was a trash person who wasn't like they seemed to be, then takes revenge and in doing so aquires a powerful skill, which then changes them to a condescending, over confident, op character that doesn't change and ends up becoming a complete asshole through the story (I've seen it, when I was hunting for good reads, after completing/being caught up with other favorites I've read)
Well anyways, to keep it short, at first i thought this was gonna be an annoying read, but it seemed to have warmed up to me, during the part when it was coming up to ch 15(10th level bass fight).
