Young Do - Joo Hee - Dong Baek love triangle was formed.

On the Monday episode of KBS' "Haeundae Lovers" Young Do (Park Sang Myun) and Dong Baek (Supernova's Park Geonil) fought for Joo Hee (Davichi's Kang Min Kyung). 

Dong Baek fell in love with Joo Hee at first sight and helped her with a set of shopping bags, coming to her rescue in her time of need. However, Young Do had also fallen in love with her at first sight just a little while ago, when she walked by him with her heels and classy outfit. He was happy to clean the road that she walked on and recite a Korean poem about spreading flower petals wherever your love goes.

But because he cleaned the floors that she was going to walk on, she slipped and fell but Dong Baek hugs her and saves her from this risk. While holding her, he introduces himself and she returns the favor.

However, Young Do is looking at this and is fuming. He glares at Dong Baek, causing viewers to laugh.
