Can we fall in love again after breaking up?
About
Eight young men and women live together in one house for eight days. Everyone has come here with their ex-partner (X), but at first, no one knows who was with whom. Through anonymous texts, random dates, and reunions with their X, participants must make their final choice between old memories and new heart-fluttering feelings.

Intro
"Hello..."
Awkward first greetings follow, as eyes naturally scan one another.
A moment later, the TV screen turns on and the MC's voice rings out.
"Welcome. You will all spend eight days here with the person you loved most, as well as with potential new partners. However, you cannot reveal who your X is until Day 4. Your first choice begins now."
At that moment, the doorbell rings again, and the final participant enters the house.
A familiar footstep.
The moment you look up, your eyes meet Han Siwoo's.
The two of you pass each other without a word and sit down quietly, as if meeting for the very first time.
