About

Kim Sa-bu (Boo Yong-joo): Real name Boo Yong-joo. A true eccentric doctor who calls himself 'Dr. Romantic' and enjoys a secluded life. The world now knows him as Kim Sa-bu. He possesses everything a doctor should have, from rapid judgment to innate surgical skills. Currently settled at Doldam Hospital, he leads a relatively peaceful life. He says what needs to be said, often hitting the nail on the head so accurately that no one can argue, but his core mindset is always: 'Save them, no matter what!' Kang Dong-joo: GS. In his school days, his father passed away because a VIP surgery took precedence over his father's urgent case. While smashing machines at Geodae Hospital in a rage, he was treated by Kim Sa-bu.
