New Girl - S2.E25

Sonny starts writing a song unaware that it's a song about her break-up with Chad. After her new neighbor and the "Patio" waitress, Mel criticizes Sonny over her music, the two decide to place a bet in order to prove that the audience will love Sonny's song. She attempts to sing it in the new coffee shop "The Patio", but fails because she is unable to perform it while facing Chad. Shortly after, Sonny realizes that the song she's written is about Chad with the help of Mel and that she still has feelings for him.
