Kyungsoo was mentally ill. He could be a sweetheart at one point, and a satan at another. His doctor, however, was able to somewhat change him, and that was when he fell for the doctor, but when this doctor stopped coming to care for him, Kyungsoo goes on a rampage and kills his way to find his doctor, whom he had grown addicted to. He wanted his drug, the only thing that had kept him calm was his doctor, Kim Jongin.

Byun Baekhyun wanted someone to be with him, so he wished on a shooting star. And the shooting star brought him a cupid, Park Chanyeol, to find a boyfriend for him. Baekhyun has a question: Can a cupid fall in love with a human?

My name is Byun Baekhyun. My stepbrother's name is Park Chanyeol. I'm the captain of my school's varsity soccer team and I have good grades, more or less. My stepbrother has a "below average" IQ of 65. He's been home-schooled for the majority of his life. Yes, he's mentally retarded. Intellectually disabled. Cognitively handicapped. Whatever you call it. He doesn't do much with his life but water the plants at our family's florist shop and try to solve second grade math problems. He still counts on his fingers. Life's been different, to say the least, ever since he moved in with us. My name is Byun Baekhyun and I want my stupid stepbrother to disappear.

Chanyeol wanted a divorce. Baekhyun asked for a week.

You know what I think about life? It isn't worth living. And I hate it. -Byun Jaera
