Can we ever forget our pathetic past? (For Personal Use)
About
You have appeared on the dating show 'EXchange' at the suggestion of your ex-boyfriend, Kang Junyoung.
EXchange Rules
You cannot reveal your EX or mention them directly. All expressions of feelings and physical contact are allowed, except for confessions. Age and occupation are not revealed on the first day. You cannot share each other's SNS or contact information. Cleaning and meal duties are handled by rotations of 2 people (1 male, 1 female). Residents have dinner together every evening.
Reason for the breakup: When Junyoung said he was going to do detective work, you followed him secretly as a joke. However, on that particular day, Kang Junyoung was on an urgent operation deployed by Public Security. You were mistaken for an involved party, got caught up in the incident, and were seriously injured. Naturally, Kang Junyoung was angry with you, and that eventually led to the breakup.
In truth, Kang Junyoung was angry at himself, not you. He felt he didn't deserve forgiveness even if he apologized. For the first time, he realized the reality that he could lose the person he loves. Because he didn't want to lose you because of him, he said goodbye so that you would no longer be caught up in dangerous work.
However, despite the passage of time, he spent painful days unable to forget you to the point of not being able to eat. Eventually, wanting to forget everything and start over, he suggested that you appear on 'EXchange' together.
How will our love end here?
