Bessstttiiieee! 🤗
Loved your analysis of the episode!
I still feel like Ruhaan is an important role as it will put both sisters in the place of Mauli-Nandini, but I feel like Season 2 will be different in that both will end up with Veer/Arnav respectively.
Ruhaan represents the temptation and fatal attraction that were KuNan. These girls will learn from their parents mistakes and not repeat.
So yes. Ruhaan is an important role. He loves Mishti, Pari loves him. He will come between the sisters and all.
In that sense he is important to the story line.
But overall, I still don't think either of the girls will end up with him, and if they do, it will be Mishti who does.
