I can't remember the name of the manhwa but I remember that the mc was a member of a mob/mafia, he wasn't the leader but he had a significant rank, he gets betrayed by his friend and then dies, with all the regrets of his past, the Grim reaper gives him a second chance and he goes back to when he was about dropping out of highschool and there's a girl he burnt with a cigarette butt that he saves, he rights the wrong so his future doesn't shitty like the last time. If someone can tell the title that will be great.
