Two male leads. One a rather fierce and sometimes bad tempered character. He often considers violence as a good way to solve problems. Even doesn't refrain from killing in some cases. The other one is a kind hearted and very empathic person only want to live his life serving people as a doctor and take care of his little sister.

Stumbling upon one another in a quite odd situation. Bad start for them as they have very contradicting points of view. Like the main characters in The Untamed.

They fast grow to like and care for each other, complement each other. The chemistry between the leads is over the top and depicted in the most intense way I've seen in Chinese dramas so far. Their relationship is very dynamic, taking the viewer along in the course of the drama. After a considerably short time they already showed that they unconditionally trust each other (a small setback aside). Even when one seemed to be betrayed on such a high level by the other, the trust between them isn't shaken in the slightest. They will risk their live for the sake of each other and the acting of both, Mao Zi Jun and Yi Bo Chen, was so authentic and convincing.

The female "lead", Chu Ran, isn't just there to pass censorship. Her character contributes to the story. She is just lovable.

The plot has some surprising twists and the main villain's character was written in a really really good way.

If you've loved The Untamed, especially for the chemistry of the leads, it's highly possible that you will fall in love with Killer and Healer.
