Sweetheart, It's Our Secret!


CEO Do Kyungsoo measures all human relationships through money, so when he accidentally gets tangled into a scandal with top star Kim Jongin, are his stocks rising or are they actually plummeting? 


Celebrity!AU meets Office!AU 




Do Kyungsoo should’ve been born as the Devil’s bastard son. 

Too bad he’s 100% human – this is a joke, right? – with red, glorious blood running though his money-making veins. He’s the type of person who aims to be on top at any measures and would use his nonexistent devil-like claws to rip through your skin and see how much you’re worth to him. Kyungsoo trusts no one but himself and thinks that mankind needs desperate help to get their together – like seriously, why in the world are they so stupid to the point of no return? He recently became the CEO of South Korea’s largest mall (“For the prestigious and maybe the desperate,” Kyungsoo quotes as he adjusts his glasses), Enchantment.

Expecting nothing less than success, Kyungsoo decides to let his assistant, Byun Baekhyun, find an attractive, -on-legs model as the Mall’s representative (“Because only the best gets the best,” Kyungsoo’s motto ever since day one of living). This is where you obviously insert Kim Jongin – famously known as Kai – Asia’s -on-legs God.

Ironically, Kai’s probably the only celebrity out there that has the cleanest record in history. Ever since debut, he has never been involved in a single scandal, and that pisses reporter Kim Jongdae of Scandal News on so many levels! Driven by motivation and the idea of becoming the top journalist, Jongdae can consider himself to be Kai’s stalker (“It’s not called stalking, it’s called fishing for money,” Jongdae quotes as he takes multiple pictures of Kai exiting the van).

However, as two different worlds are mixed together, Kyungsoo finds himself getting tangled in the most horrifying and humiliating scandal ever:

Top Star Kai is DATING Enchantment’s CEO, Do Kyungsoo!

“I don’t do idols,” Kyungsoo grunts as he smashes the keyboard, pretending to be an anonymous person on the comment section of the article to deny this ridiculous scandal. 

What’s even worse than this is when Kai shows up in front of Kyungsoo’s doorstep in less than 24 hours since the scandal broke out.

And for sure, all hell breaks loose afterwards.


“Do Kyungsoo is indeed my boyfriend, right Sweetheart?”
