Review Detail of FishForThought in Apocalypse Chaos: The Awakening of Greatest Survivor

I am more than just confused. What I’m in chap 3 and Mc just died after being an asshole to a beggar and later being beaten up by random guys. Also the woman he was just unfriendly to now wants to invite him to her party because she knows he can leap back in time?(Did I understand that correctly?) pls someone explain what is going on. You’d think he’d be more intelligent for someone who has the ability to jump through time
