Mendanai Sang Dewi ke Puncak

In his past life, a man died from overwork. Reborn as a college junior, he gained an investment system — the higher his investment rating, the greater the returns. He invested in a female classmate who, ten years later, would transform completely and climb into the wealth rankings. After his rebirth, he invested in her and looked after her at every turn. Gradually, she fell in love with him.
