Background
"Mèng zhī Sēn" is an original duet song featuring Luo Tianyi and YANHE.

This song tells about a child who had lost her mother, and also eventually lost her father to drinking problems, leaving her to beg on the streets. She hears about a dreamy forest where she can be happy and experience love's warmth. Upon arriving, she meets Calamus, a male, along with two other girls

She asks Calamus if she knew what happiness is, and the latter replies that happiness is to leave this 'world without happiness' and then invites her to a place with infinite happines. As the girl closes her eyes and smile, it is revealed that the orphaned child was killed by Calamus, and Calamus along with the two other girls beside her are left lying, dead, in their blood in the real world.
