I Accidentally Picked Up a Shadow Guard Who Wants to Kill Me. What Should I Do?

[Gentle, devoted doctor gong x loyal shadow guard shou]

Bai Hengze was once a divine physician of the Lingshu Sect. A tortoiseshell left behind by his late parents sparked endless bloodshed in the jianghu, bringing disaster upon his sect. His master, the sect leader, was forced to expel him, and Bai Hengze took the name Shen Xun and went into hiding among ordinary folk for years.

On what seemed like an ordinary night, a figure drenched in blood crashed into his courtyard. Out of a physician's compassion, Shen Xun treated his wounds. He never expected that the moment the man woke from his grievous injuries, he would turn his blade against him.

"Hey, I saved you. Is this how you repay me?"

The shadow guard attacked again and again, despite his grievous injuries and dwindling strength. At last, a short dagger grazed Shen Xun's neck, its sharp, searing pain making him furious. He had no choice but to activate the mechanisms in the room, finally driving the man away.

They met again in the prince's manor's torture chamber. The man was once more soaked in blood, and once more Shen Xun chose to save him.

"Hey, your prince gave you to me as payment for your medical treatment, so from now on... you're mine."

P.S.:

1. Mutual unrequited love, and saving each other.
