Ten years ago, Guili's first step when he first met Slim Leviston was to push him to the ground;
Silin vowed on the spot to save his face.
As a result, until the end of Guili's semester abroad, Silin was still unable to win as he wished;
So Silin took the advice of his friends and used a beauty trick to seduce him, but in the end he was tempted first——
Ten years later, Gui Li discovered that her new neighbor was actually her rival when she was studying abroad!
"Don't reject old friends so much. I'm here to make a documentary."
Ke Guili suspected that someone had ulterior motives and intended to observe his flaws.
Before anything could be seen, the two were involved in a series of murders;
Gui Li and Silin quarreled while investigating the case, but Gui Li accidentally discovered the truth about the case that forced him to leave the criminal investigation team three years ago——
It turns out that what Silin said is true, he has been waiting for the echo of departure;
Like them, they are obsessed with waiting for the response of their ancestors, knowing that they cannot still insist on waiting.
Fortunately, they finally waited for the echo——
Intention: The echo will eventually sound, just like the confession of the heart, there will eventually be a response.
