What's the name of this novel? It's about the male protagonist taking care of his hospitalized girlfriend after his rebirth and earning money after being beaten up?

" Rebirth 2014: A Warm Man's Life " told the story of the male protagonist's rebirth in 2014. After he and the disney princess escaped a wave of positive energy, he was reborn back to his youth, dreaming of becoming the richest man and regaining his love. In this novel, the male protagonist's girlfriend was hospitalized. In order to pay for the huge medical expenses, he did not want to make things difficult for his family and secretly earned money. At the same time, the male protagonist was also beaten up, but he did not live off a woman. He had to rely on his own efforts to earn money. I hope you like my recommendation.
