The story goes so:
A man went to school/university together with someone else who is in love with a girl. He gets to sleep with this girl and a lot of other girls, women, maybe also men - it is lots of meaningless sex.
Because he betryed his school mate he does not especially want to go to the class reunion. There he finds out that the girl died and his ex- school mate who was in love with her is angry at him because it is his fault. He is killed
but then he gets the chance to make everything better by living again and making better choices, one of them is that he shall try that the girl does not have to die. In this new live he remembers everything from before and when someone wants to have sex with him he does not do it just because he is bored anymore. He manages to just be friends with this girl and so on, at the class reunion, one of his school mates says he is now married and happy and in the life before he had sex with that girl too and it was not so happy...
His friend tells him at the class reunion that the girl (that died because of him in the other life) will come from the airport or something like that and then the mc remembers that it is the day the girl died in the life before so he calls her and tells her to stay away from danger and runs to her help. He manages to save her but I'm not sure if he himself dies or not because he was already killed in the life before. Maybe his other self will live on instead?
Please help me find this manga!!! I want to read it again!
