What would make a perfect man?

Anything but her current neighbor. 

Kwon Soojung is a journalist, which mean she is very good to point out which one is a good news which one is a bad news. And her neighbor—unfortunately—fall on the bad news side. With his golden looks and silver tongue, Oh Sehun can make every female he walk by pass out in instant and he knew that. Fortunately for Soojung, she is immune to all of that. Finding her ex-fiancee ing one of her bridemaid on the day of their marriage knocked her off enough to know men like him are dangerous. 

But, she can't help but to seek help from her neighbor when her friends, one by one, being murdered.

How to shut up an annoying female?

Throw his garbage basket on said female's yard.

Oh Sehun is a cop, an undercover cop. That's why instead of flirting with the beautiful Kwon Soojung, he has to stick with his role - which is a bad bad newcomer. Unfortunately for Sehun, those hips of hers that will swing gracefully everytime she walk away from him and those lips that part innocently whenever she is surprised plant themselves permanently in his head and that's a big no to his job. Yes, she is kind of sarcastic, but he is not one to ignore such assets given by God's generous heart. 

And, he doesn't like it when the female he swears to own being shot right under his nose.
