After Going Bankrupt, My Brother Handed Me Over to My Mortal Enemy

Sweet romance + one-on-one couple + devoted to each other + mutual devotion + older, fatherly boyfriend + extra sweet The Su family goes bankrupt, and the eldest son, Su Shaoan, decides to go abroad to earn money and pay off the debt. So he sends his younger sister to live with his archenemy. Xu Moting stares at the little dumpling in front of him, completely speechless. If he hadn't owed Su Shaoan a favor, he wouldn't be stuck playing big brother to someone else's little sister. Xu Moting plans to look after her for just one year. After that, whether or not Su Shaoan has come back, he won't have anything to do with Su Su anymore. But when the year is up, Xu Moting is completely won over. The little dumpling is soft and sweet, and the first thing she says once she can talk is "Big Brother." Xu Moting at first: "Take your sister back in a year." Xu Moting one year later: "Su Su, please don't go!" Xu Moting: "I didn't mean to fall for her, but she calls me Big Brother... No one has ever called me that in my life." Xu Moting's cousin: "Cousin, am I not a person?" Su Shaoan returns home with money and a thank-you gift, ready to bring his sister back. Then he hears his archenemy call him brother-in-law. Su Shaoan: "I've ruined my sister's whole life!"
