MBC Monday/Tuesday drama "Triangle" (script Choi Wan Kyu, director Yoo Chul Yong, Choi Jung Kyu) finally ended. This showed the lives of three brothers that had grown up into a police, a gang member, and a conglomerate.

Kim Jae Joong played the role of the second brother Huh Young Dahl. Huh Young Dahl was the gang member. It might've been because they were so severe that the other gang members would avoid them. Kim Jae Joong saw that Huh Young Dahl was maturing and this was drawn out in the most natural way. In the drama, there were a lot of conflicts shown and he also showed various sides of Huh Young Dahl.

In the beginning of the story, the life of Huh Young Dahl acted by Kim Jae Joong was unbelievable. He was having an affair with a married woman and was caught by her husband. Cursing and violence were necessary just like breathing. It was only natural that he would then do things that would be like "trash." Kim Jae Joong's acting was Huh young Dahl itself.

Aftewards, Kim Jae Joong expressed a more mature Huh Young Dahl. This was the first growth of the character.

Meanwhile, "Triangle" is about three brothers that separate after losing his parents and live for twenty years without even knowing the existence of each other. As they reconnect as brothers, the drama portrays the story of their love and success.
