Myungsoo is on the cusp of graduation, he's got great friends a cushy home life and a lovable (and a little overprotective) older borther. The only thing really missing from his life is a significant other, he doesn't mind too much though because he already has so many people he loves but occasionally he feels a pang of desire when he sees his brother and his boyfreind. 

Basically Myungsoo's life is normal and for the most part uneventfull.

Sunggyu lives life on the questionable side of the law where his days are spent mostly drinking or fighting, people flit in and out of his life on a daily basis never leaving a trace as they go, the only person Sunggyu has in his life realistically is his 'friend' Sungyeol who's been busy. Sunggyu lives a pretty lonely life but that's the way he likes.

He's never been sorry for the way he lived his life before, he's never wanted to change either.

Till he meets myungsoo that is. The boy is incredibly trusting and naive to the point it could be considred stupidity but there's an endearingly sweet charm to him that sunggyu cannot seem to deny. All of a sudden his life seems like a sorry mess and things get crazy and tangled as myungsoo sees all the things he doesn't want him to see. Sunggyu's afraid he'll discover his scars.

Myungsoo can't get sunggyu out  of his head, he's far from the usual people myungsoo meets, crazy and wild and slightly dangerous but there's a charisma that myungsoo finds himself draw to. An inexplicable magic in his presence that draws him closer and prompts him to be curious about everything because sunggyu is smart and better than the life he's living. Myungsoo wants to peek into his carefuly gaurded heart. 

Hoya's an overprotective and over paranoid older brother who fawns over myungsoo and if he was allowed to would lock him in a tower gaurded by a dragon because if there's one thing he's not willing to budge on it's his brother getting into a dangerous sitauation. And he sees sunggyu as a dangerous situation, hoya will do what's best for his brother whether he likes it or not.

Sungyeol is hoya's boyfriend who's a lot less strict than his partner, he's come to love myungsoo like hi own little brother but rather than opting for a 'hoya role' he decides he's going to help myungsoo along his crazy adventure because he knows hoya can sometimes be too paranoid for his own good and he sees the way myungsoo stares at sunggyu.

A shy, naive myungsoo, a bumbling belligerent sunggyu, a dissaproving and overprotective hoya and a scheming, interfering sungyeol. Does this love story even have a chance?
