MC was the only one who is alive in 100th life which is current lifetime of manhwa at the end of round 20. After final round he make wise turn back again and  That life which is his 101th lifetime he made 97 players survive and can able to wish. All the sh*** was plays of g**'s who are Gaia and Chaos. MC will kill them make them and other gods who are part of it that survival game like what they did to humans . Also MC actually never goes back past it was like parallel world . So actually there was 101 world lines. He gain Kranos power which is time and space so he created 102th world line which his family alive and there was no survival game . But his powers stay still. FL of his original or current life is Juri .at the last side story MC understand that he actually love her after all hardships they lived and can see also that how always Juri loves him so much and sincerely. He directly propose lol . They married and have 2 kids which have age gap between first and second child is 16 lol. In side stories MC goes other world lines which 100th life of his and 96 other wordlines of other players which their wish comes true

Also I feel like the "cockroach" bas**** should've been punished more for what he did but it was her choice of conditions so fine i
