Further, she said, "Yeh Hai Chahatein deals with another social issue. It’s often said that it’s easier for men with children to get married again, but very tough for a woman with a child to find a suitable groom."[12]

Abrar Qazi expressed, "I feel very fortunate to be working with Ekta Ma’am. I have been watching all her shows since childhood and it was a dream to work with her someday. I didn’t know my dream would come true so soon in my career but I feel blessed. I was in complete awe of her when I met her for the first time during the briefing of our show."[13]

Sargun Kaur Luthra stated that she took inspiration from Neena Gupta for her role.[14] Talking about playing a mother for the first time, she said, “When I was told that I will be playing a mother, I wasn’t apprehensive at all. My only worry was that i am very young and I had to look mature on the screen which was a challenge. The team has helped me a lot to help me look a certain age and moreover with my body language to portray this character. Even Vidhaan (my on-screen son), has helped bring out the best in me. More than mother-son, we are like friends off the screen.”[15]

Aishwarya Sakhuja was roped to play the negative role of Ahana which is her first negative role. Speaking about it she said, "I have auditioned for a lot of Balaji shows and whenever I auditioned for negative roles I was told I look very positive. So, when I bagged this role, I asked them why now? They said eventually you will get to know as to why we have chosen you, and I understand because they like to surprise their audience and that's exactly what they are doing. I was figuring how to go about it, but my team is helping. After every two sentences out of habit, I go into the positive zone but I have people to handhold me and help me,"[16]
