Hello. I'm with another forgotten title. It's all my bad memory T.T Man was from big business family. He had an experience of wins and losses working at family business. The main problem of the life wass that he loved someone not good. He was dead. (I think it was somehow related to this lover but I don't remember, really.) After that he reborn at the same world in past but in different body. This body had even better background family although he was a tradh of this family. He suggested help his younger self. All in all, they would have marriage contract. He was seeing how difference between them was raising with time... His former lover was reborn too. At the end of story this lover revealed MC's rebirth to ML (younger self).
