I Debut While Supporting My Older Brother

A famous idol who dies over and over again, and his younger brother who gets swept up for no reason and regresses with him. "Please, I just want to die of old age now!" The younger brother did everything he could to stop his brother’s regression, but it was all in vain. Eighteen years old, once again. Just as he was contemplating what method to try in this life... "Are you interested in becoming an idol?" "Not my brother, but me?"
