The man is a ceo of a big company. He has been in love with this girl since high school, then he hears she's getting married and he dies at the wedding. Please help
Can you add more details? Edit: like for example if it's CN or JP and if he got reincarnated in another world or past
Can't remember if it was a jp or cn. When he dies he goes back to when hes a high schooler or middle schooler and then restarts his life over
