**ok i make Taemin girl here :) his name's the same **

Minho; a certified notorious playboy opted Jonghyun's (his bestfriend) sister Taemin to pretend to be his girlfriend to make his (Minho's) crush who Minho believes to have a thing on him jealous and broke her relationship with Taemin's childhood crush.
 

This is a win-win situation atleast for Minho. 

He believes that when the plan pull through, Minho will get Krystal and Taemin will get Kai.

But what if Taemin and Minho suddenly felt some spark between them?

Will they just pull through with the deal or be together for real??
