Be careful of what you wish for.

Seohyun and Kyuhyun were dating, but it was hard for them since they are both idols, especially of popular groups. Sometimes, they even fought because of their frustration.

But on one night, they have a big fight and she yells something she didn't mean to say and really shouldn't have said.

Through the night, the world turns into an alternative universe.

What if they never met?

What if Kyuhyun wasn't in that car crash?

What if he wasn't part of Super Junior?

What if he had become something else that his father completely approved of?

What if he never fell in love with her?

She wants to go back to the way things were. Back when Kyuhyun was the evil maknae. Back when he sang his heart out. Back when he was part of Super Junior. Back when he loved her.

And only she, and a couple of friends, can turn things back to normal.

But how do you do that when the one you're trying to get back doesn't know you anymore?
