Xu Nianze, the second-year top student at University B, is tall, handsome, and from a well-off family, single and heartbroken. When he came to University A to communicate, he found that Xin Jing, a junior girl he had been dating for 7 years, not only did not recognize her, but also looked completely different from the two before. What had she experienced? He hesitated for about three seconds and decisively decided to pursue her, but he only had 21 days left, so during these 21 days, he arranged very intensively to do experiments with her, watch horror movies, host parties, receive foreign friends, and even go on three-way dates with his mentor's children. Of course, there were several heroic rescues. His passion melted the glacier in her heart little by little, revealing a shocking secret beneath the sea: it turned out that she had not forgotten him, but was unwilling to remember her former self; it turned out that he was not a scumbag who disappeared after chasing him for 21 days, and there was a deep redemption hidden behind his pursuit. It takes 21 days to develop a habit; it takes a lifetime to love you.
