The battle for Jo Yeo Jeong's heart has begun. 

On Tuesday's episode of "Haeundae Lovers," Lee Tae Sung (played by Kim Kang Woo) and Choi Joon Hyuk (Jung Suk Won) started to compete with each other for a chance for Jo Yeo Jeong's heart.

Go So Ra awakes to remember how she and Lee Tae Sung kissed at the pool while slightly drunk from alcohol. Then Lee Tae Sung appears and says, "Are you starting to remember yesterday when we..." So Ra interrupts him, saying, "Don't you know that a drunk kiss doesn't count? There are lots of mistakes made when drunk, so just look over this one."

Lee Tae Sung says, "You don't know but maybe you and I were born because of alcohol, so do we not count? Anyway, our contract began. For the next two months, we're going to deceive everyone and act as if we are married." She retorts, "We're just appearing to be couples and there will be no physical contact."

Then Choi Joon Hyuk comes to find her. He takes her to a coffee stop and asks what happened and she tells him everything, even lying to him as well. Then he says, "I waited for you for a while," expressing his disappointment. He says, "I was trying to get to you but I guess he was quicker." 

Then Lee Tae Sung calls and she tells him that she's with Joon Hyuk. Lee Tae Sung gets jealous and tells her that she is a married woman, to which she quickly hangs up the phone. Choi Joon Hyuk says, "I came to buy the Haeundae Hotel. You won't be able to get back his hotel in two months because I'm going to have it." So Ra declines, telling him that she can't just cancel the promise, regardless of what will happen in two months.

Yoon Se Na (played by Nam Gyu Ri), who still believes that Tae Sung is dead, appears at the bar that the three of them met at and talks with So Ra while Tae Sung is away from his seat. She expresses her disdain for him and how he has never been dedicated to her. 

Near the end of the episode, Choi Joon Hyuk tells So Ra about his feelings once more. When she tries to avoid him, he holds her and says, "I want to give you my feelings but why do I have to hide them because of a fake marriage?"

So Ra tries to calm him down but he tries to kiss her forcefully and Lee Tae Sung sees this.
