Before the wedding, some are in pink, some are in blue.
Reconciled after a long separation, Tae-kyu (played by KIM Kang-woo) and Ju-young (played by KIM Hyo-jin) plan the marriage. But Tae-kyu accidentally finds that this is not Ju-young's first marriage and calls off the marriage? For 7-year-old couple So-mi (played by LEE Yeon-hee) and Won-cheol (played by OK Taec-yeon), to get married each other is more than natural.
Falling into 7-year-itch So-mi takes her last travel before wedding, and these she meets fresh love.
After unexpected one-night stand, Dae-bok (played by LEE Hui-joon) learns that Ira (played by KOH Joon-hee) is pregnant. Dae-bok proposes Ira happily, but she is not sure if they're life-long mates.
In every man's enviousness, Keon-ho (played by MA Dong-seok) will marry the hottest Uzbek girl Vika (played by Guzal Tursunova). Perhaps she is so sexy; Keon-ho loses his confidence as a man at night.
There's only 7days left for those couples, will they be able to tie the knot happily ever-after?
