Does anyone know in which episode does this happen?

I saw a beautiful clip of Raman making marriage vows to Ishita.

(If the above link doesn't work for you just search for "I will be there for you, ever, my love!'" in Hotstar)

I have been trying to hunt for the episode where this happens but no luck so far. Can anyone help?

It's a S12 E1 IN HOTSTAR
