Surprise, surprise! �Episode 15 of MBC's 'Triangle,' which aired on June 23, had a pleasant surprise for fans as T-ara's Jiyeon made an appearance as a potential partner for the chaebol�son, played by ZE:A's Siwan, in a marriage of convenience. �

His wealthy and influential father brought in Jiyeon as an attempt to get Siwan's mind off Baek Jin Hee's character, who is considered an unworthy addition to the family. �When the two see each other in his father's office, Jiyeon tells Siwan, "Hello. �We last saw each other in Las Vegas, so it has already been two years."

As he clearly seemed displeased at this turn of events, she tells him in the hallway, "You must not be in a good mood." �Siwan responds, "I don't see why we are meeting right now." �She says, "You're as foul-tempered as ever. �I'm going to create a reason, so don't worry. �Let's go drink coffee."

It seems likely she will appear again, so stay tuned for more interactions between the two in 'Triangle'!
