Black Cold Wave

After a class reunion, Cheng Yiying is kidnapped. Her abductor is Gao Qiu, the person everyone talked about most at the reunion.

Gao Qiu killed someone six months ago, but escaped criminal punishment because he suffered from intermittent mental illness. He was confined to a psychiatric hospital with extremely tight security, but after an accident, he escaped.

Gao Qiu is not only mentally ill and a murderer, he is also Cheng Yiying's ex-boyfriend.

Gao Qiu doesn't believe he killed anyone. He kidnapped Cheng Yiying so she would help prove his innocence.

But although he wants her to prove his innocence, he won't let her leave. She is imprisoned in a cold, damp room.

Gao Qiu gives her only one phone, and Cheng Yiying can use it only when he is there. She must use it to overturn a murder case that has already been settled!

It's almost impossible.

But to stay safe, Cheng Yiying has no choice but to cooperate with Gao Qiu.

At the same time, she looks for a chance to escape her cage.

But as the truth gradually comes to light, Cheng Yiying discovers that the real cage has only just closed around her...
