A two-way secret love. The gentle and kind-hearted Jiang Yu and the affectionate and tough academic Ji Yanran had a secret love in high school, and they have a deep emotional bond with each other. Ji Yanran's good friend Tang Xin failed the college entrance examination due to family changes. She resorted to an extreme method - to death, and morally kidnapped Jiang Yu and forced him to become her boyfriend. Jiang Yu chose to compromise out of his sense of responsibility and reverence for life, but this caused his relationship with Ji Yanran to fall into a long period of depression and pain. In college, Ji Yanran wandered downstairs from Jiang Yu due to a conflict in the dormitory, and was seen by Tang Xin making a scene and jumping off the building. After everyone's persuasion and ridicule, she finally quit. The two finally experienced the beauty of love openly. Upon graduation, Jiang Yu's family arranged to go abroad, but Yan Ran was unwilling to accept the Jiang family's sponsorship and chose to stay in the country to work, and the two broke up. A few years later, Ji Yanran was going on a blind date. After Jiang Yu learned about it, he returned to China and began to pursue Ji Yanran again. He was delighted to find that they were still where they were, waiting for each other.
