A murder involved the two of them. Lu Yu, as a policeman, was chasing the murderer, while Xia Wanqiu was a suspect.
In order to investigate the truth of that year, Lu Yu was determined to bring the real culprit to justice. And Xia Wanqiu, a high school student who seemed to have nothing to do with the case, unexpectedly became a key suspect in the eyes of the police.
In the process of tracing the case, Lu Yu gradually discovered the unknown connection between Xia Wanqiu and the case.
Because of Xia Wanqiu's brother, the two lived together. As the investigation deepens, the relationship between the two is also quietly changing.
After a trial, the superiors decided to abandon this pending case, but Lu Yu still insisted on pursuing the murderer carefully behind the scenes.
He finally gave up on the truth.
This case may not need the truth because...
The truth is just an "I love you" lie.
Returning after many years, I never imagined that loving you has become my instinct.
