Kusum Dola

Five years later, Roopkatha, now a college professor, meets Emon, now a successful doctor, to invite her to her wedding. Later, she meets Rono who has abandoned living with his family as well, to discuss her marriage preparations. Secretly, Roopkatha plans to reunite Emon-Rono by remarrying them on the day of her wedding and their twelfth marriage anniversary. Meanwhile, Emon receives the Konya Rotno award. Emon, as per Roopkatha's request, manages to bring the Chatterjees to Roopkatha's wedding, much to their distaste, as all assume that Roopkatha is marrying Rono. However, Roopkatha surprises everyone by introducing Alok as her groom.

Emon and Rono have an emotional confrontation, marking their reunion, sorting out all their differences. His family members also realise his innocence and reunite with him, welcoming him and Emon back into their family. Lastly, Roopkatha, taking the heartfelt apologies, blessings and good wishes from the Chatterjees, marries Alok, marking a new phase in her life, as the series ends on a joyous note.

Screenwriter Leena Gangopadhyay[17] who has previously written down the script for Bengali TV shows like ETV Bangla's long-running drama series Sonar Horin and another daily soap Binni Dhaner Khoi, Zee Bangla's partition-themed love saga Keya Patar Nouko, and Star Jalsha's serials Ishti Kutum and Jol Nupur ; developed the central idea for Kusum Dola, whose premise was initially based on a love triangle.[3]

She made the main female protagonist, tentatively named Shimul, a village girl who is bright in her studies and quite upfront by nature. Circumstances force the girl to marry a man (the lead hero), who is previously committed to another woman (the third main lead). The story follows the man's story to get over his feelings for the other woman and how he finally falls in love with the heroine (Shimul). Ganguly decided to have the backdrop of an extended family, and had the other woman (named Roopkatha) marry the hero's brother and live in the same house as the hero (named Rono).[16]

Rishi Kaushik who had previously collaborated with Ganguly and Banerjee in their production Ishti Kutum,[18] was selected to portray the lead role of IPS Ranojoy Chatterjee a.k.a. Rono. Later Rishi said in a 2018 interview that his character "Rono" is reserved and headstrong like his real-life self.[19] Aparajita Ghosh Das who had been playing the heroine in another TV serial Kojagori (on Zee Bangla), was cast in to play the other prominent lead character, Roopkatha, taking into account her onscreen chemistry with Kaushik.[20] Actress Madhumita Sarkar, noted for her portrayal of Juni in medical romance-drama series Care Kori Na, and Pakhi and Khushi respectively in the romance saga Bojhena Se Bojhena; was cast to portray Shimul (later named Emon).[21]

The series premiered on 22 August 2016 and replaced Prasenjit Chatterjee starrer Mahanayak TV series and was telecast everyday on Bengali GEC Star Jalsha and its corresponding channel with HD feed, Star Jalsha HD. It is available via optimum cable connection or by satellite TV connections. The show has been distributed by Star India, in association with Novi Digital Entertainment. On the digital platform, Kusum Dola is available for viewing on the app Hotstar. New episodes are released earlier than on TV, and the service is available for viewers having a premium subscription plan.[1]

The show has been filmed at several locations, the most prominent being Kalimpong.[22]
