Du Jun confesses to Hui Won in front of Min Uk! Her heart races with bewilderment and a mixture of excitement and embarrassment. After avoiding Du Jun at work, Hui Won finds herself forced to be with him. Meantime, Min Uk worries about whether or not Hui Won will accept Du Jun's confession...

Hui-won activates the elevator emergency system and saves Du-jun from danger! Du-jun falls even deeper for Hui-won. Meanwhile, Min-wook, realizing his feelings for Hui-won are not friendship, but love, declares war on Du-jun and begins to make serious advances toward Hui-won.

Du-jun sees Hui-won and Min-wook together at the OB/GYN clinic. Hui-won becomes increasingly concerned about Min-wook's presence, and the misunderstanding deepens. Hui-won, too, is secretly resentful of Du-jun's absence from the clinic, and is distraught by Min-wook's confession.
