病弱妹妹总是肖想我

Xu Yulian is the eldest daughter of a wealthy family, smart and beautiful. Her life should've been a smooth ride, until she ran into a stumbling block named "Xu Wenjiao." Her sister came out of nowhere and became the person she hates the most. When she was a child, the frail Xu Wenjiao occupied all of her mother's time and attention. After she grew up, Xu Yulian had a crush on the neighbor girl who had just returned from studying abroad. But before she could get up the courage, she saw the girl confess to Xu Wenjiao instead. In this house, it's going to be either her or Xu Wenjiao, one or the other. Xu Yulian got so angry that she actually packed her bags to leave home, but her sister, who always seemed so weak and frail, suddenly grabbed her by the wrist wrist and pushed her into the corner. Xu Wenjiao looked at her jealously and whispered in her ear: "Sister, why do you like her but not me?" Xu Yulian blushed, "Xu Wenjiao, are you crazy? Have you been reading too many bad romance novels to be acting this way?" (Source: Bilibili, translated)
