Why Yug wants to be with Gauri?

yug has not met Gauri, he just heard her which is assumed to be Gauri singing. He is keep meeting Kaali again and again.he even said that Kaali is his lucky charm. He likes Kaali too.

He thinks, that voice is his true love ! In his mind, he is committed to that voice/girl. It's almost like, he is in a relationship with the voice. Lol. I know it sounds funny.. But.. It's how we are when we believe we are committed to someone in our heart . Hehe. But him and kaali are just too good for each other ! Hope he realizes.. She is that girl whom he is looking for !! :) :)
