Review Detail of Masta12 in Guild Wars

i dont get it. He was NTR'd, died and reincarnated to the past, he was supposed to get revenge and such blah blah, but suddenly, he change his mind after he realized that it was petty. I only read chapter 40 yet, I felt confused already. I mean, whats the point of reincarnation? is he the MC? or the girl? or both cuz they both reincarnated? It started great really, but after pulling some plot twist such as 'evil god mannipulating them' it sucks.. Adding and giving him some buffs, epic treasures, items, reputations and such wasnt bad but giving him everything was plain boring.
