Deep in My Heart.

Overseas student Zheng Yihua and her native Korean classmate Soo-ok are bosom friends. Suspecting appendicitis, Zheng is rushed to the hospital for an emergency operation performed by Lee Sang-hyun. Soo-ok falls head over heels for the surgeon, who ironically takes a fancy to his patient. The romance turns the friends into foes. An embittered Soo-ok ruins Zheng's reputation with malicious gossips intended for Zhang Zhen, Zheng's father's personal assistant and the daughter's fiancé during his business trip to Korea. The wary mother of Lee demands the girl's parting from his son. Answering her lover's plea, Zheng stays, quietly enduring the scorn rained down on her from the mother. Having had enough of slander and accusations, the foreigner returns home, vowing never to return. Even the blessing from Lee's father fails to change her mind. Lee arrives at the airport, looking forlornly over the runway where the plane takes off.
