One of the key strengths of Yeh Hai Mohabbatein is its well-developed characters. Ishita, the protagonist, is a strong and independent woman who fights against all odds to be with the man she loves. Samar, on the other hand, is a romantic and caring partner who stands up for his love and family. The supporting cast, including Shagun, Raman (played by Sidharth Shukla), and Aaliya (played by Tina Datta), add depth and complexity to the show.
