Rucha plays a menacing sister-in-law to the female protagonist in the show. She says she has never played such a character earlier.
"I play a character called Mahima in the show. She has a very overpowering and overshadowing nature. She is a decision-maker and knows how to get her work done in any possible way," Rucha said here Friday at the show's launch.
"Basically it is a grey character and I have not played such a character till date," she added.
For Rucha, it will be a challenge to portray the role as she says, she has always played innocent and simple characters.
"Playing this character will be a challenging experience for me as I will get an opportunity to emote a different emotion," Rucha said.
"So far I have only played (a good) bhabhi, girl-next-door or a gullible or simple, docile girl. So somewhere, it is a wonderful opportunity for me and I will give it my hundred percent," she added.
Rucha's last negative role was in the TV show "Saas Bina Sasural", but she was there only for a few episodes.
"Do Dil Bandhe Ek Dori Se" features Arhaan Behl of "Pratigya" as the male lead, while Mansi Srivastav makes her small screen debut as the female lead. Vikas Sethi is paired with Rucha.
