Myungsoo was new nurse in rehabilitation center, at first look he may seem shy and innocent, but when you get to know the boy better you find out his true nature. Myung was all playful and he liked to joke around a lot, even most of his jokes was erted outside of work. Behind this youthful face was hiding a real man, who knew what he wants and what he deserves, but even Myungsoo was really talkative, social and sweet person, there was something he tried to hide... 
Myung was sick, since childhood already and that was one of  the reasons he always blocked his heart for others. Not that he was scared to fall in love, but break other persons heart.  In years his sickess had got even worse, even thought doctors tried to help him, it seemed impossible... they always got into impasse, but he never give up his hopes for normal live. He always lived with hope to get better, to have a normal at least one day. When Myungsoo realized that there is nothing with what he can help to himself, he decided to help others. Becoming nurse was one of the little dreams that came true, but working in hospital didn't seem as interesting as he wanted it to be, but as he heard about rehabilitation center not far away from city, Myung knew that it should be the right place for him.

Hoya was doctor, with a little experiance already. He seemed mature from his look, probably because dancing and working out was one of his hobbies, but never talk about book just from it's cover. Inside Hoya was also sweet and nice, but at the same time he was shy and his cheeks seemed to turn red more than he would like when he talked to others. But after meeting the boy, he quickly learned how to play along his jokes and discovered new side of himself.
