B2ST's Yoseob and 4minute's Gayoon sing 'The Night Watchman's love theme 'Hope'
The pair sang "Hope", the love theme song for theMBCdrama. The pair are the main vocals for their groups, and their voices harmonize beautifully for the song! The song is a pop ballad that starts with a classic piano melody. Until the chorus, the melody is solely played through the piano and the acoustic guitar, adding more to the mood of the song.
