Lee Tae Sung and Choi Joon Hyuk are going head-to-head.

On the Tuesday episode of KBS' "Haeundae Lovers," Tae Sung, played by Kim Kang Woo, and Joon Hyuk, played by Jung Suk Won, begin their quarreling over Go So Ra, played by Jo Yeo Jeong. 

Joon Hyuk comes between So Ra and Tae Sung, who had come to a small road-side bar just to see her. Tae Sung suggests that they face-off against one another. 

The two of them begin drinking, trying to outdrink the other and by the end, both of them are incredibly inebriated, their words slurring. 

Tae Sung says, "Hey you! I don't like you very much, especially that weird creepy glare of yours. Really don't like that," explicitly stating that he doesn't care much for his contender.

Joon Hyuk then says, "Me too. I'm just holding it in because you're probably going to marry her."

Then Tae Sung says, "Who me? With her?" as if he is shocked at the accusation. He then tells Joon Hyuk, "Don't be calling out women who already have someone to yachts and making them drink wine and stuff."

Joon Hyuk, who then realizes for the first time that So Ra and Tae Sung are not fiancés or married, says, "That's up to me. I have the right to do so. You're nothing you really shouldn't be bothering me with this." 

Tae Sung, who is currently experiencing amnesia says, "If you knew how difficult my life is right now, you wouldn't be saying cruel things like that to me," with a look of utter desperation, yet it was a fresh comedic relief. 

In this episode, Tae Sung and Joon Hyuk both express their interest with So Ra and it is clear that the two will begin to really compete for her heart in the coming episodes.
