There might be lesser hype on Kim Joon and Gook Ji Yun who has less meatier roles but thanks to the high popularity enjoyed by KBS2TV Boys Before Flowers, it has helped them to become more recognizable among viewers and especially advertisers. Kim Joon plays Song Woo Bin in Boys Before Flowers and is very much an under-developed character (the yo-yo-yo accent doesn't count) compared to the other F4 members. Gook Ji Yun is the leader of the JinSunMi trio, Ginger who terrorizes Jandi whenever she appears on screen but is otherwise rather insignificant and has not been seen since the ski resort scenes. But the drama has opened up doors for them and both recently inked a 1 year deal with Korean casual fashion brand, Omphalos to be their main models for 2009. According to a Omphalos representative who explained their decision to choose them, "Kim Joon projects a confident and positive image while Gook Ji Yun also fits in nicely with our brand's image." The both of them filmed a commercial and photoshoot on 3rd February where they had acted as a couple (maybe the drama PD can consider, but probably too late) for the brand's Be Love campaign. Before the shoot begun, the staff held a surprise party for Kim Joon whose birthday fell on the same day (poor guy has to work on his birthday). Omphalos sure has some fate with Boys Before Flowers as Lee Min Jung who currently plays Goo Joon Pyo's fiance in the drama was their main model for 2008.
