But then something unexpected happened. He rushed out the moment he went back in time, hoping to change the tragedy of Little Jinpei's father's death and give him a happy childhood. But he tripped over a rock, lost his memory, and spent half a month in the hospital. As a result, Little Jinpei had an even worse life than in his previous one. He'd realized in his previous life, when Little Jinpei died, that Hagiwara Kenji loved Matsuda Jinpei. But after starting over, the six-year-old didn't understand what love was, and it wasn't until he was in his twenties that Hagiwara Kenji realized his feelings for Matsuda Jinpei weren't just a pet owner's affection for a cat. Years later, after finally regaining his memories, Hagiwara looked back on his life: 1. Built an intelligence organization that covered Japan's underworld (? ) 2. Became the second-in-command of the so-called biggest and most evil criminal organization in Japanese history, the Hirin Group, and successfully cleaned it up and brought it into the light, turning it into a multinational corporation that raked in money every day (?) 3. Became a national-level doubles player alongside Little Jinpei (?) X. Earned enough money to keep a cat (x) X+1. Held the wedding of the century with the world's most charming number-one supermodel, Matsuda Jinpei (x) P.S.
