My Sister, My Best Friend, Cared About Me Since I Was Little, Until I Went to College

[Senior sister + single heroine + daily love life + campus + living together] Lin Shen, who had just entered college, never expected that he just wanted to move out of the dormitory, but instead moved into the apartment of his sister's best friend Chi Anyu. What's even more unexpected is that Chi Anyu has been thinking about him since he was a child, and didn't start taking action until he was admitted to college! This female professor, who is cold in the eyes of others, actually has many faces in private. In the morning, I would ride a bike to take him to school. At noon, I would ask him to come to the office to have lunch and take a break together. In the evening, I would give him some small benefits to tease the innocent older boy! Lin Shen felt that Sister An Yu was too kind to him, so kind that she didn't even look like a sister. Until one day, Lin Shen discovered that Chi Anyu not only wanted to be his sister, but also wanted to be his wife! … "Sister An Yu, how could you fall in love with your best friend's brother?" "You're still asking me? Who told my parents that he must be my husband in the future?" "Sister An Yu, you don't want your teaching materials to be easily soluble in water, right?" "Teaching staff? I stayed at Suida just to wait for you. My sister has lost her job and I will still support you!"
