He is gentle and considerate, and he is as close as father and daughter to Lin Xi's four-year-old daughter, and the three of them gradually develop a warm relationship. However, the calm was broken.

Amidst love and lies, Lin Xi must choose: let him go and return to the world of intrigue, or face the unknown storm with him.
