Upcoming film 'Marriage Blue' revealed its official couple posters of 2PM's Taecyeon, Lee Yeon Hee, and more! The movie portrays the relationships of engaged couples who get cold feet the week before their wedding. The posters show the Tae Kyu (Kim Kang Woo) and Joo Young (Kim Hyo Jin) couple and Won Chul (Taecyeon) and Oh So Mi (Lee Yeon Hee) couple looking as happy as one can be, but the story tells otherwise. Tae Kyu and Joo Young have been together for 12 years and broke up once before, but on the week before their wedding, they discover each other's past affairs that could potentially break them apart. Won Chul and Oh So Mi also have a long dating history of 7 years and naturally decide to get married, but Oh So Mi feels like there is no more heat between them. She also follows her fiance's suggestion by quitting her job as a nail artist, but secretly enters a nail art competition where she falls for Kyung Soo (Joo Ji Hoon). 'Marriage Blue' will premiere on November 21!
