Worried about her graduation project, Su Xiao wanders into a strange antique shop and accidentally spills her blood on the owner.
The owner wakes up and claims to be Taotie, an ancient ferocious beast sealed away for a thousand years.
And Su Xiao’s blood is the only key that can break his seal.
From then on, this cold-faced boss corners Su Xiao against the wall, makes her sign an “art sponsorship” contract, and forces her to live with him.
Other people send flowers and bags when they date. He, on the other hand, casually devours a miasma demon and spends a fortune at an auction to win a magical artifact for her.
Su Xiao thinks she’s just a tool, a “key,” until he loses control of his power protecting her and massacres everyone in sight.
He wipes the blood from the corner of his mouth and holds Su Xiao tightly in his arms, his voice hoarse:
“Don’t be afraid, my little girl. I’ll spoil you myself.”
