Yoon Jeonghan — he is your husband and your doctor at the same time because he's a doctor, whilw you're a nurse. You both are the youngest doctor and nurse at your hospital at the age of 23 (him) and 21 (you). He's really handsome, young rich man, kind, caring, taller and older than you. Aside from being professionals at medicines/science/health, you and him are a party person, mostly you. All he does at a party is only to drink alcohol since he has a high alcohol tolerance.
