Firstly, the focus should be more on Ravish-Atharv than Ravish-Vividha because that's what it's meant to be so when Atharv kissed Ravish on the cheeks, it made everyone smile.
Where as the clear love angle between Atharv-Vividha was highlighted at its best. The soulmate waali feeling, Vividha just knows her Atharv is in pain because they are one person as said so by the woman herself today.
She is so fiercely protective over Atharv, her 'jaan lelungi' said it all. She can kill for him.
Atharv? The natural instinct of sensing his lady love in danger brings him back. Did you notice how Vividha wasn't even surprised at his behaviour? It's like she knew he would protect her. Like I always say, there's invisible thread binding them. Their instinct is to PROTECT each other!
