I Like You, Rainbow Idiot! 

나는 당신에게 무지개 바보처럼

Kim Jongin had always thought that he was straight, he dated many girls before to prove it. He was the only straight person - besides Suho - in their group of six friends who were all homoual. Jongin, better known as Kai, is very attractive. He could have any girl falling for him if he wanted to, so to say, he was the ladies man. 

Oh Sehun is homoual. He dated many men before, ones younger and ones older. Despite his uality, he was accepted by people from both genders. Weird, right? Well, even though he was interested in men, he wasn't girly - much - and played sports. For girls, he gave great advice to them. Oh, and he has rainbow hair. Gotta love that hair. 

So I'm guessing you know where their whole story is gonna start, right? With the straight man suddenly falling for the rainbow boy, things can get retarded easily when another pair of six guys come into the picture!
