Tagline: My feelings for you are free
[Poor Rural Kid x Rich Spoiled Kid]
On a trip to Guizhou for a poverty alleviation survey, university professor Tang Heng encounters his "dead" boyfriend Li Yuechi.
Here, he discovers the truth behind the suicide of their old peer and Li's incarceration.
"You pronounced me dead, Professor Tang?"
"..."
"Were you a faithful widow?"
"Shut up."
And so Li Yuechi sealed his lips with a kiss.
