Stubborn, inhuman jade-stone top (A) x alluring jade-mine owner bottom (O)
Shi Yu is rich, an Omega from a family that owns a mine, and never short of strong, strapping Alphas.
He is good-looking, too: tall, with a narrow waist and long legs, and sturdy enough to kick a frivolous guy so hard he cracks both his nuts.
His family had just taken on a new mine. A blast from the explosives revealed a handsome man, dazed and covered in dust. Shi Yu happened to be there to supervise the work, and when he caught the man's scent, he sniffed.
What a delicious-smelling Alpha.
Unfortunately, the handsome man seemed to have taken a hit to the head in the explosion and could not even remember his own name. He did nothing but toil away at the worksite, or, after Shi Yu tricked him into coming home, toil away there instead.
He wanted neither a title nor much money. He just followed Shi Yu around, watching him from the shadows.
Shi Yu thought taking him in was a pretty good deal.
Shi Yu: Hey, today's rough stones are worse than the last. If I run out of money, I'll have to sleep with you...
No money, no sleeping together?
Qi Yan heard only the key words. With a dark look, he went out, found a top-quality stone, and brought it back to put by the bed.
Shi Yu: ...All right, now I have money again. Come on, let's sleep together.
