Heart Ache: The Hardworking Mr. Fang

Fang Zhihan stared at her for a while, seemingly thinking of how to respond, when Yu Gangan bent over and asked, "Are you thinking about throwing away my keys?"

The man's lips curved upwards slightly into a smile, "Sweetie, thank you for giving me a good idea."

Yu Gangan smiled and said threateningly, "If you really do that, then I will immediately revert you back to singledom."

"Then I'll have to study the Stockholm effect," Fang Zhihan laughed.

The Stockholm effect, also known as Stockholm syndrome: a hostage complex that causes a victim to have favorable feelings, dependence, etc. towards their perpetrator.

"Look at what you're saying. I am a doctor. How could I let you get sick?" Yu Gangan held onto his handsome face and squeezed it gently. "To cure you, I will try all different kinds of herbs. I can't guarantee what effect that will have on you."

Both spoke with underlying meanings.

It was a sweet threat.
