The most disobedient and playful devil is sent to Earth as punishment for breaking all the rules in Hell. The only way she can ever return to Hell is to complete a mission. A mission which requires her breaking up 100 couples in 250 days. Easy for a devil with skills? Maybe. Or maybe not. By the 190^th day, she has already broken up 99 couples. All that’s left is one couple. And her target is her Best Friend and Boyfriend. However, after going through a series of incidents, she starts wondering if she could ever complete her mission…

THE CHARACTERS

DUSK a.k.a KIM RUE EN

Stubborn and playful, Dusk broke the rules in Hell and needs to break up 100 couples in 250 days. With the help of her devil buddy, Dusk takes the form of Kim Rue En, a girl with stunning features and is the hot topic amongst guys. Her fighting and acting skills are awesome and her only weaknesses are that she is messy and she loves food so much. She doesn't trust the word ''love'' and does her mission with no feelings left behind.

BACON a.k.a BAEKHYUN

Known as the smartest and best looking devil in Hell, Bacon would help his best friend, Dusk, no matter what. Hence, when she is punished, he begs the Head to let him help her on her mission. Should she not be able to finish her mission on time, he too would be punished. He takes on the form of Byun Baekhyun; a cutie pie and player in a Kingka Group, EXO.

PARK CHANYEOL

Part of the Kingka group, EXO. Despite his seemingly cheerful personality, Chanyeol does not warm up to strangers easily and when he has a first bad impression of someone, it is difficult to change the way he thinks of that person. However, once you know him well, Chanyeol is the most cheerful of the lot and trusts people easily. He is loving and caring to his girlfriend, Oh Min Ri.

LIGHT a.k.a LUHAN

The Angel-in-training in Heaven had failed majority of his examinations and the only way he can ever go back to Heaven is to find the Relationship Wrecker, Dusk, and perish her to prevent her from breaking any more couples. He takes the form of Lu Han, a flower boy and he joins EXO Academy, where he is immediately recruited into EXO due to his good looks. 

OH MIN RI

Naive, kind and innocent, Min Ri is often envied due to her sweet relationship with Chanyeol. She's really pretty, but she prefers to read instead of dolling herself up, hence, she is labelled: ''NERD''. However, no one dares to bully her as EXO would always stand up for her. She is Rue En's first friend on Earth and would help her anytime. She trusts Chanyeol completely and promises to share her woes and happiness with him. However, she has one secret that no one, not even Chanyeol, knows.

EXO

The no.1 Kingka and flower boy group in EXO Academy. They have two sub units solely for emergency purposes, namely EXO-K and EXO-M.

EXO K consists of Suho, Baekhyun, Chanyeol, D.O, Kai and Sehun, whereas

EXO M consists of Kris, Xiumin, Luhan, Lay, Chen and Tao.

Most of them are players, but they are really smart and have the closest bond ever.
