I have an idea.. how about heeseung fake dating Jaeyun because of hee's grand mother last wish is wants to see heeseung's girlfriend (Jaeyun here is female).
Heeseung n Jaeyun is actually rival in their college. Rival in academic. They always compete in so many ways..always have arguments over silly things. But actually Jaeyun is falls in love with heeseung but hide it with sarcasm.
When heeseung ask his friends to be his fake girlfriend, they recommend Jaeyun to be his fake girlfriend..
Jaeyun agreed to be hee's fake girlfriend, Jaeyun's friend help her to dress up for hee's family meeting,
To be shocked, all hee's family members n grandmother accept Jaeyun warmly even they like Jaeyun immediately because of her polite, and softspoken attitude. They always ask heeseung to invite jaeyun in every family events, such dinner, shopping, or family trip. Heeseung starts see the other side of Jaeyun and starts falling for her.
After sometime heeseung actually confess to Jaeyun that he loves her and become real couple.
