Donghae is a young doctor in an emergency. He's true sweetheart, always ready to help his patients, friendly to his colleagues and everyone adores him. He's single and homoual but none of the people around him seems to mind (except for many ladies who just can't resist his charm and say it's a pity because they would love to date him), a few of his male colleagues even flirt with him openly, on a daily basis. However, he always says that he's waiting for the true love. His life seems to be calm and arranged but what will he do when he happens to meet a very handsome, a very flirtatious and a very erted patient named Lee Hyukjae?

Doctor, I have a problem, it's an emergency. My heart is beating very fast when I see you, doctor. Could you help me, doctor?
