Retired Professor: Matchmaking for Rejuvenation

An 82-year-old music professor transmigrates into a withered old man, lying in a nursing home waiting for death. The system activates: match one true couple, rejuvenate by one year! Help a lonely elderly woman reunite with her ex, black hair regrows three inches. Humming a song casually goes viral, shaking the music world: 'Qin Wannian' returns? Beauty producer Dong Na investigates and finds him teaching square dancing songs. Playing the fool, system in hand, rejuvenation is no dream. Pop stars mock him? Disciples betray and frame him? All get slapped down. From ICU to concert tours, from old man's shirt to global tours, using songs to tie red threads, sweet and satisfying!
