Cheng An and Ji Yan had a close friendship as childhood sweethearts, but unexpectedly lost contact after graduating from elementary school. Ji Yan, who had always been a good student when they met in high school, was rescued by Cheng An from a group of gangsters.
When they met for the second time 8 years later, Cheng An also became a stranger to Ji Yan.
Ji Yan is not a good person, and Cheng An is even less so. The two not-so-good people redeem each other and use their remaining sincerity to fill the gap of 14 years.
Concept: There is never a relationship that can be started in vain
