Marriage is a whole new thing from dating. In dating, you're free and not really committed. As in marriage,it's quite the complete opposite. You're committed and not really as free as before. 

 

Myungsoo and Krystal are stuck between marriage and dating. Both are happily dating but both don't want to get married. 

 

More trouble arise, when Myunsoo's parents want him to get married within the year, more specifically, they want him marry to his girlfriend, Krystal

 

What will the couple do? Choose marriage or rather choose dating?
