"Another Self in My Heart" is the opening song of the domestic 3D cartoon "Ye Luoli, Dream of the Soul" sung by Zhai Yanan. The melody in the song is very special, and the prelude to the slow song is very suitable for setting off the atmosphere. Zhai Yanan's gentle and sweet voice sounds as dreamy as anime. The lyrics express that there is a fairyland full of dreams, and growing children need to find another self they want to be, so they feel very imaginative.
