Minho and Taemin being cousins are childhood companions and lived in a joint family all their lives. The undesired marriage has put them in a war like situation. Both Taemin and Minho are against the marriage as the paper marriage was done as per wishes of their dying grandfather without taking their consent. Taemin has dream of joining London School of Economics for higher studies after his BBA while Minho has done his share in business and is currently beginning to settle his father's business (Taemin calls him unemployed for his own ego). 

However, they play pranks on each other, bicker, irritate the living life out of each other just so the other could voice out the need to end this marriage before their parents and grandmother. Amidst their squabble, long-distance relatives decide to play their part in their rollercoaster of a life by marking their attendance in the approaching wedding. 

Before the proper wedding, which was due in a month, they both vow to steal the peace away from their household. Either in revenge or just to get labelled as 'not each other's type'. 

But when you're made for each other, are destined to be together; whatever you throw at fate, it boomerangs right back. 

Do they succeed in making their demand of divorce past the heads of elders before the awaited day or......fate plays them once again?
