Young love is as clear and transparent as crystal, but it is also fragile and difficult to survive like glass.
In the Internet age, Jing Hao and Ruoxuan, who live in the south and the north, have become acquainted with each other and have known each other through their youthful high school years. However, Jing Hao, whose college entrance examination application was inexplicably tampered with, failed to go to University C as promised. The two still fell in love long-distance in college. However, Ruoxuan, who later faced a misunderstanding about a breakup and was disfigured in a fire, finally chose to go to a foreign country to lick her pain alone. Can Jing Hao, who has been frustrated along the way but still persists in finding love, find Ruoxuan and rekindle his love network?
