This is the kind of story where the MC will beat someone up then cries about it, hears any story then cries about it, or anyone that speaks to him then proceeds to cry about it. Seriously, why are Koreans so obsessed with beta male characters? It's fine at the beginning where we expect character development later on, but MC still behaves and acts the same.
At another point, I laughed at some of the art where the MC has a huge muscular body but with a small baby head. It looks so out of proportioned that I couldn't take the scene seriously.
