Qiao Ning'an never imagined he would see that man again.
An accident leads to him moving into the home of the most powerful man in the empire.

Qiao Ning'an: “Colonel, could you bring me a rose next time you come home?”
Gu Qichi: “Mm.”

Qiao Ning'an has a secret. When he was sixteen, there was someone he loved very, very much.
Qiao Ning'an: “Gu Qichi, I really, really like you. I love you.”

Gu Qichi: “Qiao Ning'an, will you be my colonel's spouse?”
Qiao Ning'an: “I will.”
