With respect to age - there's no definitive look for any age right? Different people look different at different stages of their lives. Priya looks 30 to me, and Ram looks 35. The age factor is okkayish I guess. Like someone said, it's not the age they are promoting. That time, they were promoting love after marriage when you are in that middle - ageish category. This time they are honestly promoting second chances at love. - that's the crux. How they move on from their respective love failures and love each other after marriage.
It can be taken either way. My point being Nakul and Disha are not looking the age they are shown
