As the story says Madhu is compelled to act that means RK will not make her heroine. Something will force her to act may be return of 40lakhs / bad health condition of Shamsher or Padmini. This Avinash may be a director or hero who will help Madhu to become a heroine, could be rival hero for RK. Later RK will find Madhu's letter and regret listening to Dips Kamina! Or may be Madhu will act with RK as heroine under Avinash direction.
This Avinash will be a nice character but start to love Madhu without knowing anything.
We will see glycerin in Madhu's eyes in the coming episodes. đ
