Review Detail of nureha in Apocalypse: The Fat Lady Strikes Back

I have honestly read this novel. /spoilers/ how do you say this, the development of the FL is quite slow, and different from other apocalyptic novels, the story doesn't start with the existence of zombies(they will appear later on, but it's still far away) but the sudden change of environment(?) or emergence of disasters(?), making resources scarce. the FL has a physique that easily gets fat just by drinking making her hated by her family (not her father included since he wasn't really there when the story sort of started). the FL has an older sister who is a total opposite of her. they aren't really close and I honestly think that her sister is selfish. so, the FL is a victim of bullying and when she started fighting back she gets murdered and suddenly resurrected. the FL's powers honestly comes from her fat, fat is her source of energy and when she absorbs energy she always gains weight. I don't remember every details but the person who defended her is the ML. I actually skipped through a lot of chapter, the novel is still unfinished and have +700 chapters.
