Personal references in the characters?

I don't know about other actors but with Surbhi I think the writer has used some of her personal characteristics while writing her role Bela.

Her OCD for one example. Surbhi has mentioned that she has OCD. In the show it has been highlighted that Bela...though being a Naagin who literally moves on the dirty streets with her hood...has OCD. Yesterday when in Kitchen Champions she gently prompted one kid to wipe his mouth after eating...it was very funny. Her OCD jumped out. 😆 Arjun then said to let it be as kids eat like that only.

Another thing I have noticed is that snoring has been highlighted in the characters that she has played... Bela and Meera Kapoor from Tanhaiyan. Maybe she does snore in real life. 😆

I haven't followed other actors...but are some of their real life qualities too used?
