She will take over from the main protagonist Saroj played by Dolly Sohi.
"This was a generation leap. Bhabhi (Saroj) has taken sanyas and is going to find herself. She tells me to take over her values and her ethics. She also asks me to take care of the family and keep it intact."
"Too much of drama is going to happen," Rucha told.
"Bhabhi", which has been running for more than two years on the channel, revolved around Saroj, a girl who finds her life changing drastically after marriage. Now Rucha will defy the beaten path and bring freshness to the serial.
"I am not going to play a typical bhabhi (sister-in-law). I will play a modern girl who goes to office, looks after the business and also takes care of her family."
She was seen as Kali, Kumud's shrewd and scheming half-sister, in Ekta Kapoor's soap "Kkusum". It was a negative character but she enjoyed playing it.
"I like both kind of roles because I get to portray different shades. But 'Bhabhi' is a difficult and challenging role for me. It is too much of a responsibility for me, as I have never played the key role. "Viewers are also going to find it difficult to accept me as bhabhi for the next few months. But I have taken it as a challenge." Rucha is doing only "Bhabhi" at the moment.
She says: "It's a 12-hour job for me as the story is going to revolve around me. So I am just concentrating on this only."
Asked her whether she is interested in films, she replies: "There are many plans for the silver screen - I got a few offers but I couldn't do it because I was stuck with 'Kkusum' then. Now, waiting for the right kind of role."
Not new to the arc lights, Rucha started her career as a child artiste and appeared in films like "Dancer", "Hum Hain Kamal Ke" and "Kanyadaan". She has also modelled for advertisements.
"I did a couple of moves as a child artiste. I also did a serial and then took a break to complete my studies," she says.
