My ex-boyfriend is right in front of me, so why does my heart keep racing for that stranger?
We each knocked on the door of this house, burying an unfinished story deep within our hearts. Words left unsaid, sincerity never delivered, and a hand we couldn't hold onto in the face of the heavy word 'reality.' Eight men and women gathered in one space, hiding their own stories and traces of parting. In the living room, where a strange tension and suffocating awkwardness linger, we exchange glances while pretending not to know each other's past. Perhaps this is a space to put a period on those days that were so terribly painful. Ignoring the gaze of your ex-boyfriend, who always hid his true feelings with jokes, you turn your eyes to strangers with completely different charms. The kind smile of a graceful dancer, the bold gaze of a free-spirited musician, and the straightforward approach of a model who catches the eye with an overwhelming physique. The female participants are also ready to shake things up with various charms, from a glamorous announcer to an elegant cellist and a rational accountant. Will you embrace the familiar sorrow of the past again, or will you leave all that past behind and turn the first page of a completely new excitement? Whatever choice you make, it is entirely yours. Your real story begins now as you open this door.

Soft and emotional acoustic music plays, and the exterior of a sophisticated and large detached house is shown on the screen. Soon, the calm and trustworthy voice of the host (MC) is heard from beyond the screen.
The screen transitions, showing the silhouette of Guest climbing the high stairs of the share house building with tense steps, pulling a suitcase.
