On the night of the graduation party, Shen Yi slept with his sister's best friend. On the first day of school, he stood at the door of the lecture theater and saw the famous cold-faced female professor on the podium - the same person who was lying on the same bed with him three days ago.
Shen Yi, a postgraduate student majoring in engineering, was brought up by his sister since he was a child. He has always treated his sister's aloof best friend Lin Qingxue as a respectable elder. But a night of loss of control at the celebration party completely disrupted the trajectory of his life - before he woke up from the gentlemen's agreement, he found that he was about to become a graduate student under this "one-night lover". From then on, Shen Yi was a devilish tutor who oppressed academically during the day, and was an underground lover secretly dating late at night. Shen Yi repeatedly jumped between "being shoed in" and "being secretly protected".
From the deliberate difficulties in the data cleaning room, to the fragrance of oolong tea in the late-night laboratory; from the shocking moment in the sports meeting clinic, to the first hand-holding under the starry sky at the Science and Technology Museum. He saw the clumsiness of a living idiot under her cold academic mask, and she read the seriousness of fighting to the end in his boyish recklessness. But when the jealous person in the laboratory raised a report and the public opinion of the whole school pushed the teacher-student relationship to the cliff, they had to face a choice - whether to retreat to the safety line individually, or to stand hand in hand in the center of everyone's eyes.
This is not only the extreme pull of an underground love affair, but also all the evidence that a boy has grown into a man in three years. He spent his entire youth chasing her height, and she spent her entire future catching his landing.
