Participants sing on stage, receiving cheers and evaluations from the audience. However, defeat here does not simply mean elimination. Someone's survival, fate, and even their feelings for one another become part of the stage.
The most beautiful song is not necessarily the one that survives.
On this stage, will you survive, or will you remain in someone's memory?
