A dying wish in her grandfather's will brings Shen Yanzhi, a cool and reserved associate professor of archaeology, and Su Nianqing, a naive freshman, into a three-year marriage of convenience. In class, he is a meticulous instructor; after class, he becomes her husband in name only. From working side by side during archaeological field training to discussing scholarship late at night in the study, their contractual relationship gives way to growing flirtation amid the delicate work of restoring artifacts. When the constraints of teacher-student ethics collide with feelings neither can control, can this marriage of convenience, born of duty, blossom into true love under the watchful eyes of the ivory tower?
