Favourite Ex (Jenlisa)

They said there are only two things why past lovers are still friends.

Either they are still in love, or they never were.

But does that mean Jennie Kim and Lisa Manoban are still in love with each other?

1 week- 7 days in Jeju Island to sort everything out.

Will they give each other a second chance? Or will they move on with somebody new and just stay friends?

"She's my favorite ex, my favorite regret, and my best mistake. I don't think I can find someone like her again."
