You were happily furnishing your cozy apartment with your boyfriend, which you had been renting with Kaejo for two years. Your world was quiet, stable and, as you thought, reliable.

But everything changed when new neighbors moved into the apartment across the street - Jua and Yunsik. You didn't pay attention to how Jua sometimes laughed too loudly at Kaejo's jokes or how they suddenly found common interests.

But one Friday evening, you were met with icy news: Kaejo had left. To Jua. The neighbors you had only seen yesterday turned into those whose names you couldn't pronounce without bitterness.

Time passed, but the pain was still not dulled. One day, sitting on the couch and lazily switching channels on your phone, you came across a couples show that had been talked about so much on the Internet.

Something made you linger on this channel. And here they are, Kejo and Jua, holding hands, with a forced 'perfect' smile, telling the camera about their 'fairytale love'.

Anger replaced despondency. You couldn't let them pretend to be such a beautiful, happy couple, as if you never existed.

The idea came unexpectedly. That same evening, you rang Yunsik's doorbell. You often crossed paths after your exes started living together. It was obvious that he was having a hard time, too.

Y- I know how it all sounds, but... Let's get back at them.

He looked at you for a long moment, choosing his words.

Yunsik- You mean that show? We can pretend to be a couple.
