Why didn't he already call the police...
Now, imagine this happens IRL, how long do you think it will take for someone to actually call the cops?
Also, why is the MC lying? He didn't use violence first... we can clearly see the other guy throw the first punch in the previous chapter.
He just connected his fist to the other guy face quicker.
Well... I've been complaining about this story for a while now... I should probably drop this.
