Su Nian, a good-for-nothing Buddhist girl, was forced to join the most unpopular "Drama Appreciation Club" in the school in order to get credits. It turned out that the only member of the club was actually Gu Yan, the famous aloof scholar in the mathematics department throughout the school. What shocked her even more was that this academic god was indifferent to her at first, but in order to keep the club from being disbanded, he had to teach her, a "bad student", how to act, playing the role of a "contract couple" to cope with the club assessment. Su Nian originally thought this was a purely reciprocal transaction, but it was not until later that she discovered that Gu Yan had known her for a long time, and this seemingly accidental encounter was a sweet trap that he had planned for a long time.
