Ra-im goes over to Joo-won's to ask him if he was the one who listed her as the raffle winner, but he denies any involvement and firmly shuts her out.

Ra-im, Joo-won, Ssun, Oska and Seul revolve around the MV shoot and the hotel, as conflicts among them heighten to a breaking point.

Joo-won and Ra-im wake up in each other's bodies. Greatly confused, they try to find a way to swap themselves back, but nothing seems to work.

Ra-im and Joo-won, still trapped in each other's bodies, have a rather acerbic first encounter with Joo-won's mother at his place.

The tension between Oska and Seul rises and falls as they reminisce on the good old days when their love was sweet and the future bright.

The moment Joo-won becomes drenched in rain, Ra-im's and his souls are miraculously swapped back into their own bodies. Ra-im gleefully takes off.

Oska struggles in the aftermath of the plagiarism scandal, while Joo-won proceeds with his new project to build a healing resort.

Joo-won tells his mother that his relationship with Ra-im is a mere fling and that there is no possibility of their ever getting married.

Joo-won's mother promises Ra-im riches to let Joo-won go. But when she realizes that she won't be able to buy her off, she threatens to fire Joo-won.

After the accident, Ra-im wakes up in Joo-won's body. She cries over her own unresponsive body, where Joo-won's mind may be trapped forever.

As the ice in Yoon Seul's heart slowly melts, Oska is ready to make a full comeback. Meanwhile, the 21-year-old Joo-won is falling for Ra-im again.

Joo-won stands up to his mother, and he and Ra-im sign a marriage license. Meanwhile, Oska's back in full sway, with Yoon Seul by his side.
