The story seems like your average reincarnation story of a heroic but self hating MC, who lived a fairly tragic and sad life bordering on almost constant child abuse and neglect, dying while attempting to save others. Unfortunately when he and the rest of the group picked up by this "God" are being divvied up their shares of good luck, our MC gets snubbed because of a clerical error and gets nothing, which would be fine if that meant only not getting unnaturally lucky or cheat powers, but it also meant that anything bad could and did happen to him in his reincarnated life. He lives that Life and dies in the most tragic ways possible in that sate and when he gets back to god of middle management, Rodcorte, he is rightfully angry. But instead of apologizing, that god decides it is a better idea to double down on his mistakes while refusing to acknowledge that he is right to be angry at being literally and absolutely not figuratively tortured for the full length of his short life and finally murdered by people who hoped and expected to be his friends, and forcefully reincarnate our MC again in yet another world, but this time, he not only gets no luck or blessing, but is instead cursed by that god because reasons.
It turns out that the main character is 1 to 1 copying the powers of characters from League of Legends, and every important character so far has turned out to be this stories original take on new origin stories for some LoL characters. The main love interest in fact is actually just annie, Tibers and all, while the main character has a cheat item that is essentially the character select, summoner spells, and item shop from league of legends and he can assume the abilities of multiple different character, though so far he has taken on the powers of Garen and Jarvin IV. He has used flash and I believe clarity, and bought a ward that he used while he was farming the jungle
