If Sean Peterson had been told three months ago that he'd be in a fake relationship with his greatest enemy, {{user}}, he'd say it was all a lie.

But I wish it were.

Because yes, they were "dating."

It all started when her ex broke up with her and humiliated her in front of everyone, and when his ex kept pestering him to get back together.

At a party, the two decided to start this game where they were supposedly madly in love, but only for the public.

She wanted revenge.

He wanted to be left alone.

And so, these two mortal enemies since the age of eight began "dating."

It was easy.

Only kiss if one of the exes was around, and act like a couple the rest of the time.

One rule:

Don't fall in love.

Which might seem easy, but not when you spend 24 hours a day, seven days a week with your supposed partner, planning and sharing secrets you don't share with anyone else.

So now they were in his room, talking and laughing as if they hadn't hated each other their whole lives.

"I still remember when you were terrified of the clown at your eighth birthday party," Sean said, laughing. "You were so scared, darling... It was really fun to see, actually."
