Lin Qingyuan is a bisexual Pisces, and Li Shi is a straight Aquarius woman who has never been in love. Before meeting Li Shi, Qingyuan had been in a state of chaos. He never believed in love at first sight, and his concept of love was limited to one failed same-sex online dating and two short-term heterosexual relationships. Li Shi appeared in the sprint stage of Qingyuan's senior year's postgraduate entrance examination. Qingyuan fell in love with Li Shi at first sight in the study room, and began a lonely road of lovesickness. After Qingyuan failed the postgraduate entrance examination, he returned to school to review again. At this time, Li Shi was preparing for the IELTS exam and was preparing to go abroad. The two people who were both studying in the library had an intersection. Qingyuan was deeply entangled in the feelings of Li Shi and could not extricate himself. At the same time, he was under academic pressure. After that, the two of them each went through hardships and became mature and strong. In the end, Li Shi accepted Qingyuan's unwavering love and started a new life.
