Yet I never see the same love and care from Payal. Okay she doesn't know that Arnav blackmailed Khushi into marrying him but she does know about Shyam. Shouldn't she check on Khushi once in a while to see how she's doing, with Shyam hovering around all the time? She could even suggest telling the truth now...and reassure Khushi that nothing will break up her and Akash. If Khushi has Payal's support, no doubt she would be stronger. Instead, Payal is too worried with impressing her mother-in-law and husband to care about Khushi.
Look at the difference between Anjali and Payal. Anjali's bond with Arnav is so strong, its like she pays more attention to him and Khushi than her own marriage. She is always spying on ArHi and trying to bring them together. In fact, she cares too much...we actually say she is nosy and needs to mind her own business. But at least she cares. Payal is on the opposite end, she NEVER thinks about Khushi. She doesn't even bother asking Khushi how her marriage is going. Even though Nani, Anjali, Mami and Shyam have all noticed there are problems between Arnav and Khushi. But Payal is in her own world. I guess that's what happens when its your adopted sister.
