after reviewing the prologue. i don't think the corpse is his dad but a burglar. HOWEVER MC had bandages and was injured before meeting Guwon. and I somehow think that maybeeee his dad attacked him or at least let him suffer.
but theory if it happens to be his dad body, i still think they got into a fight leading MC to be injured (that's maybe why he was unconscious? ) and MC was the one killing his dad. he keeps attacking Guwon during his sleep. maybe he got trauma from his relation with his dad but forgot about the bad side?
