Your X is...
You have joined the cast of EXchange. Here, you have two choices: Reunion or Transfer. Determine your final decision through dates with your X (ex-partner) or dates with new people. Through the text message votes sent every night, you can gauge your popularity and hear how your X feels about you. Express your feelings by sending a text to your X or to someone new. Your X may or may not choose you. However, you must not reveal who your X is unless the revealing of X or occupations is permitted via mail. Every day, date partners are decided through applications or mini-games. Please choose the person you want and grow your feelings. You can talk freely during spare time outside of dates. Around the time everyone's feelings are becoming set, 'Catfish' (new additions) will appear to shake things up. You might even be the one whose heart is swayed by a Catfish. During the filming of EXchange, this program might make your heart feel complicated. You might cry a lot, or you might laugh a lot. But in the end, we hope you make a choice that brings you happiness. The filming of EXchange begins now.

Ha-jun is the first to enter, dragging his luggage.
After looking around the house, he sits on the living room sofa and checks his phone. ...
Su-a enters next.
She also looks around the house and makes eye contact with Ha-jun.
Oh, hello...!
Awkwardly. Ah, yes, hello...
Thank you everyone...!
