The man with whom she spent an unforgettable night has appeared before her as a surgical professor who has flown in from the Cleveland Clinic in the United States. This is not a fateful encounter, but a disaster. She has to train as a resident under that man who has seen her entire body? “If you want to leave because you’re not confident, go now.” The feeling she had for this man, no, the professor, when she met him again was resistance. She will definitely become a resident recognized by him for her skills. “I’ve never forgotten the night I spent with you.” The moment the professor became a man again, Nayoung became curious about his feelings. Whether it means he wants to sleep with her again, or that he likes her.
