I think that with time all the family members will be happy with the relationship.
Aai and Baba will be over the moon.
Kaki will be glad and by the time Naina has finished with Verdant and Aku, they both will be individuals that have realised their self-worth and made a positive contribution to their life and the family. So Kaka will somehow be pleased.
Maybe Rohini might be slightly jealous of the closeness of the relationship but I dont think she is a bad individual. She just portrays a human character with many shades of colour: sometimes good sometimes slightly shady.
I agree with Guju angel. This shows strength is its simplicity and portayal of characters that are quite true to life and therefore, the storyline will reflect that as well.
As for Verdant, I know he currently is a pest and has an infatuation for Naina but I think when he comes to know that Daksh and her are together or that Daksh does like Naina, I think he will grow up pretty quickly. He, like Aku, love Daksh very much and just like Aku had a realisation of Naina's true value and a realisation of her faults when she overheard how Naina respected her connection with Daksh; likewise I think Verdant will step aside or asist Daksh and Naina's relationship.
