Summary
Kim Soohyun is a diagnosed psychopath, he doesn’t do feelings. But when he stumbles upon this strikingly beautiful man with one particular pair of soft brown eyes, what sparks in his frozen heart is a newfound curiosity. But that takes a dark turn when he learns that his muse belongs to the same group of people that he despises— law enforcement.
Even after knowing the truth, what he feels for the detective is an insatiable craving, a twisted want rooted deep in his core that grows into something more sinister as time goes on.
So what if they stand on the opposite sides of the law? If he decides that Shin Jaemin is his, then he is, as simple as that.

Summary
When Cha Jungwoo and Kim Hoyoung’s popularity keeps rising, their agencies decide to make them into an ‘official’ couple with numerous projects waiting to be completed.
For the past few months, Hoyoung has been looking forward to it—one, because he’ll be working with Jungwoo, an actor he knows from their previous drama, Secret Relationship. Two, because this means he’ll get more exposure for his own portfolio.
There’s only one catch: their contract lasts for three years, and Hoyoung isn’t sure if he could always be professional around Jungwoo after their constant on-screen ‘relationship’...

Summary
Shin Jaemin has been fortunate and unfortunate at the same time.
One, he works with Kim Suhyeon, a man he secretly has a crush on. Two, that man happens to have a fiance—who’s very pampered that Jaemin has to accompany him shopping for groceries. How fantastic!
When Jaemin finds that little minx kissing Suhyeon on his cheek, he has had enough! He will move on from Suhyeon, probably even play around with that particular assistant manager, and forget all his miserable love life for good!
Unless...?

Summary

Summary
Wet, brutal sounds - skin against skin, fists into flesh - echoed in Daon’s ears. Muffled. Dull and distant, as if he were submerged underwater. He sat crumpled on the floor, where Suhyeon had shoved him aside with the same hands now destroying someone else.
Or the one where Daon and Suhyeon get freaky after he basically kills someone.
