Rebirth: Mother-Daughter Training

For some reason unknown, I was reborn. The day after my wife divorced me, I woke up to find myself back in 1999, when I was in the first year of junior high school. With the exceptional memory from my previous life and the advantages of being reborn, I became a billionaire by the time I reached my senior year in high school. I owned two private hospitals in City Z, five nightclubs, and several other companies. The ideal of most time travelers is to enjoy a life of luxury and power. While I have no interest in power, my little brother down there is already demanding his rights, and it's time to indulge in the pursuit of women.
