Comments of chapter undefined of My Triling System

Now author please explain to me why the fudge all of this happened. The MC literally stole and ran away from his father that took care of him for 16 years and was trying to help him with training and finding a way to fix his problem, neither the wizard nor the disciples acted poorly to him so far, if you just leave this as it is, it's bad writing, plain and simple. Maybe he was mistreated and bullied? Maybe he's a villain ish MC? You should develop on that before doing this so it doesn't feel as rushed. I hope something wrong happens and he learns that his father was just trying to help him or smth, that type of character development.
