Are you asking what song is in the music box you gave me in the drawer? "Forgot".

According to the query on Kugou Music, I learned that the lyrics are excerpted: How could you forget that you said you loved me first? There is a music box you gave me in the drawer. Have all the happiness been taken away by you? "Forget" is sung by Zhou Linfeng, written by Zhang Junbo, and composed by Zhang Junbo.
