My Brothers Who'd Go Through Fire and Water for Me Always Want to Tear Off My Disguise

In the 31st century, technology has advanced by leaps and bounds, and humanity has set foot in outer space.

The world has changed dramatically, but human evolution has stagnated. To break through this bottleneck, the biotechnology company Polo funded a project to extract special elements from different species. The result was the "Numbered Factors," substances the human body could absorb to gain new powers.

Numbered Factors have both benefits and drawbacks. To control the crimes caused by their abuse, the Bureau of Special Category Personnel Supervision and Control (BSSCP) was established.

Years later, during a BSSCP operation to wipe out a criminal syndicate, a key figure whom the bureau's administrators revered vanished without a trace. His fate remains unknown.

Several years passed. Then the missing captain quietly reappeared, with a completely new face...

After working himself to the bone and going undercover for years, he finally took time off to catch up on sleep, only to be jolted awake by a phone call. He had somehow become the prime suspect in the chairman's murder!

Forced to change his appearance to evade the manhunt sweeping the city, he became "Bai Yeshen." But just after he finished disguising himself, someone kicked open the door. The intruder was none other than his rival from police academy and love rival, Qin Chusheng!

To get away and catch the real killer, Bai Yeshen claims to be Qin Chusheng's mistress. But Qin vows to tear off her disguise, and in the process uncovers an even more shocking secret...

As they dig for the truth, the two gradually become "inseparable." Before long, rumors start spreading that Qin Chusheng has fallen for someone else's mistress!?

"Other people get locked up in the station... So why are you keeping me 'confined' at home? In your bedroom? And sticking to me every second?!"
