Cao Xue and Cheng Yao are college classmates. Cheng Yao only knows that Cao Xue's family is rich and she is the daughter of a group company boss. Cheng Yao comes from the countryside and her parents are farmers. But this does not hinder Cheng Yao's parents' determination to raise a child! Seeing that their child had good academic performance, her parents saved her money and sent her to college... The huge status disparity did not hinder the development of the relationship between the two. Because the two people were attracted to each other at the first sight. When Cheng Yao met Cao Xue for the first time, he was attracted by her temperament and ability. Cao Xue was attracted by Cheng Yao's eyes when she first saw her. Clean, thorough, open-minded, and gentle were Cao Xue's first comments about her. So under Cao Xue's deliberate contact, the two people "connected". Cheng Yao and Cao Xue dated for three years when they were in school. Like most couples, the word graduation means the word breakup. But the two of them probably didn't even break up. So on the day of graduation, the two met peacefully in a coffee shop, and then said goodbye peacefully... Until the two met again five years later...
