So I was trying to remember the novel that had this part in it and I can't remember and it's bugging me a lot. So the MC basically had a childhood girlfriend that he had tobreak up with because of her father and so the girl then became a star and when the MC was going to her concert I forgot why there was a person who came on stage and tried to stab her or something like that. So the MC saves her and gives her like a few years of life not sure how many he gave her. There was also a guy there who liked the girl and was ya know generic young master and basically when the MC saved the girl he realized his mistake and stuff I believe or maybe that was just my mind. I have an idea of the novel and I think it was Red Packet Server but I'm not sure.
