My Partner Is a Top-Rank Sentinel

Wen Chi is an S-rank Alpha who always buttons his shirt to the very top. He's gentle and refined in public, never hurrying no matter what he does. Even during his rut, he shows no change in mood, as if he has no biological needs at all.

Until one day, he dies by accident while protecting his students and finds himself in an era of interstellar chaos.

Some people are screaming and crying, while others tremble in the corner. The next second, the entire starship shakes, and a group of people blasts through the door and takes him onto their own ship.

The man who brought him there presses his head against Wen Chi's. He's begging to be marked and soothed.

Wen Chi can tell that the man's mental power is in disarray. Wen Chi isn't an Omega, but out of basic human decency, he grabs the man's head, pulls it down, and bites a tiny bump at the back of his neck.

In response, the man's body goes rigid, and he trembles uncontrollably.

Wen Chi raises an eyebrow inwardly. Not bad-looking. Since he's in this world, there's no need to hold himself back. He follows his instincts and deepens the temporary mark until the man on the table goes limp and collapses helplessly into his arms. Even then, Wen Chi still feels unsatisfied and licks his lips. Finally, he puts on his usual mask and gazes at the other man with a gentle expression.

Strangely enough, even though Wen Chi is an Alpha, his mark does seem to ease the man's outburst.

After catching his breath, the handsome man stands and whistles at him. He braces a hand on Wen Chi's shoulder, looks down at him, and wipes his thumb across Wen Chi's lips, pressing hard against the soft flesh. His expression is appraising, with a hint of interest.

Wen Chi slowly raises both hands, lifts an eyebrow, and smiles at him.

Fortunately, the handsome man takes him under his wing and gives him a legitimate identity, enough to let him get by in this world.

It seems... not bad? Wen Chi learns that the man's name is Xu Xingzhi, and that he's a powerful Sentinel. But for some reason, even though Wen Chi isn't a Guide, he can soothe Sentinels. He keeps up his former persona as a gentle and courteous man every day, until one day Xu Xingzhi comes home covered in blood, asking to be soothed.

Wen Chi expressionlessly pinches his cheek and examines him from side to side. "How did you get yourself into this state?"

But the other man simply leans against his shoulder, unconcerned. "Honey, if you soothe only the outermost layer of my mental sea like before, I'm really going to die."

So this is what Wen Chi is like when he stops pretending. Cold and controlling. Xu Xingzhi stares at the ceiling, a little dazed, then has his head turned and finds himself looking into those black eyes. But Wen Chi's eyes really are beautiful.

An outwardly refined and dependable, inwardly obsessive and cold Alpha X an outwardly carefree, inwardly kind and responsible Sentinel

P.S. This is a highly original setting.
