Although I love this song but I never looked up for the actual meaning of these two words . I always associated it with pain,grief & longing for love as shown in the song.
After seeing the promo my interest piqued up and I googled these words .CM means, " My beloved moon" or "light to my soul"
I assumed ( based on promo) ginni will be that beloved moon for aditya but watching 4 episodes I think they both will be each other's moon. Yes we see aditya's pain more because he shows it through his anger while ginni keep smiling.
If aditya needs shower of love then ginni too needs a shoulder to share responsibility.Also what is love story without some pain and longing. 😉
