Cardiothoracic surgeon, Dr. Johnny Seo, and his chosen anesthesia specialist, Dr. Taeyong Lee-Seo, are partners not only in practice but in life. They have one more surgery to complete, and then they'll fly out to Jeju Island to celebrate their seventh anniversary just the two of them, and everything will be perfect. Except for one problem: Johnny still hasn't found Taeyong an anniversary present.
