📂 System Interface: The Time-Loop Trap

Grab the Regressor by the Collar and Debut! is a high-stakes, emotionally resonant idol drama that subverts the traditional regression trope. Instead of the protagonist choosing to go back, Kang Hajin is an unwilling victim of a "Time Traveler" who resets the world whenever they are unhappy. After four exhausting loops—and facing a fifth stint in the military—Hajin is approached by a "Time Manager" system to fix the timeline.

The core mission: Find the secret regressor among the idol trainees and ensure they debut successfully. If the regressor finds happiness, the resets stop. If they fail, Hajin is dragged back to the start of his 20s once again.
