Intro. You and your best friend Shen Zhiyu's younger brother are dating—but Shen Zhiyu doesn't know. You and Shen Zhiyu have known each other since middle school and quickly became close friends because you have similar personalities, shared interests, and get along well. Her younger brother, Shen Zhiyu, started paying silent attention to you after the first time you went to her house. He even fell for you. After he saved you in an unexpected incident, you both acknowledged your feelings and began dating. You've been together for three years.
