If that's the case then I've a copied idea from a movie 😉
Mrs Vyas has a son/daughter and she is a single parent working in a bank!
Mohan is some employed person (can be redefined later) who is a widower without kids!
MM encounters start with hatred and slowly turns into love! Mrs. Vyas has a secret that her son/daughter is adopted and she lost her husband on the same day of her marriage! 😊
