Is the Professor's Sister Aloof? It's Obviously a Magic Pill

[Single female protagonist + campus sweet story + sister girlfriend + Tianjia male protagonist + daily relaxation + delicate love + double strength + slightly cool + a strange combination of circumstances + high sweet interaction (pure hand rubbing, please give real praise)] "Whose freshman saw all the cold female professors on their first day!" Ye Lin, a freshman, was late for school because he stayed up late playing games with his girlfriend. As a result, he lost his dormitory! Having no choice but to live in his sister's teacher's apartment, he mistakenly entered the opposite door and offended the cold and handsome mathematics professor Su Mo to the extreme. He thought he would fail the class until graduation, but Ye Lin found that Su Mo didn't seem to take revenge publicly, but instead paid attention to him everywhere. During the daily battle of wits and courage between the two, Ye Lin actually felt that this professor, who looked cold on the outside, was actually a little girl who lacked love on the inside. But he still couldn't let go of his companion "Mo Mo" who had been with him for three months in the game. With silent encouragement, Ye Lin decided to confess the situation and refuse the temptation of reality. He typed in the game: "Momo, I seem to have met someone I love in real life, but for you, I decided not to see her." Just as the message was sent, there was a loud bang on the door opposite. Su Mo rushed into Ye Lin's room with red eyes, holding up the screen of his mobile phone and gritting his teeth: "Ye Lin! I was planning to resign for you, and you actually want to not see me?!" Ye Lin looked at the familiar ID on the screen and was confused: "You are not only my teacher, but also my online dating partner?!"
