Forgot title but pretty sure it was about an apocalypse

#1
Okay so this guy has a friend who he thinks is the MC with a harem and he hates him. The guy is fat and has a beard. He has a hot sister and a hot mom. Anyway during th apocalypse Gods tells everyone that the apocalypse has come. Now the guy is calm and shit, he basically becomes the leader and it turns out that the girl who always teases him suddenly gets cursed. The guy looks after her nursing her back to Health. Then the guy  gets a magical upgrade and then yeah.

It's entirely possible that you mean a completely different story, but reading your description of what you're looking for...

Could the story you're mentioning be, No Respawn by jmlikestorock009?

If it's the wrong story, my bad. Otherwise, that story might sate your interests until someone else finds the one you're seeking.
