Tf is this shitty novel

is Ria (Splesia really dumb?). cause she was cursed, died reincarnated, then died again, returned to when she was young. no one irl from what we know has been cursed then died and reincarnated died again and returned to when they were young. and if what i know is true then when we die our souls are given a clean slate so to speak or we are granted oblivion. with that our memories of past lives are erased so we can move on without clinging to people that are dead or never existed in the next world.
