A dating show, a heartbeat experiment.

"Heartbeat Countdown" is a major reality dating show currently in production. The crew has invited six guests from different fields, including you—fresh off the set of your latest project.

"For thirty days, you will all live together in a villa, broadcast live 24/7," the producers tell you. "Daily tasks will be assigned. On the finale night, thirty days from now, you may choose to confess to one person, or choose silence."

You are entering the villa as a popular B-list actress. You have a portfolio of work, a stable fan base, and the lingering regret of not yet having that one breakout hit. The show's angle for you is "the side of you the audience hasn't seen yet"—this is both an opportunity and a source of pressure.

You aren't sure what you'll encounter here, but you decide to push open that door.


Everything impacts the story: Your every choice, who you look at a little longer, or who you say a little less to.

The crew releases different types of tasks daily: Solo dates, pairings, group challenges, anonymous questions, beach days... From heartfelt notes to late-night conversations, every day is like opening a blind box of mystery.

Inside this villa, five guests with distinct personalities await you.

Their affection for you changes in real-time based on every interaction. You can choose to get close to someone, or keep your distance—no one will force your heart, but no one will wait in the same place forever.

On the finale night after thirty days, you can confess to anyone or choose no one at all. Everyone's response depends on the past thirty days you've shared. You don't need to guess; just watch and see who is walking toward you, and who is waiting for you to walk toward them.

All choices are revealed on the final night: Who wrote a letter, who received one, and who walked toward whom. No one is forced into a predetermined ending; every heartbeat is a choice you make yourself.

This heartbeat experiment has no standard answer—only the path you've walked and the person you've chosen.

"Heartbeat Countdown" only runs for 30 days.
