I'm copy pasting a character sketch of Gunjan I'd put on my personal blog - see if you guys agree with me 😊
Gunjan - studious, serious, quiet. Brought up by a dominating sister and aunt - Bui and Nupur are identical twins in that department, so she never really gets a chance to speak. Nupur is protective of her younger sister, almost overly so, so Gunjan grows up timid and shy, never speaking for herself because her fiercely protective sister is always there to do so for her. In spite of the fact that Gunjan is more intelligent than her sister. But is her underconfidence also due to the fact that her older sister, apart from being protective, is also the diva of the small town they live in? Nupur is also beautiful, vivacious, flirtatious, and has a long line of admirers, while Gunjan, quiet, bespectacled Gunjan has none. No wonder her self-esteem is so low, no wonder she hides behind her books. All the adulation, the admiration is reserved for her sister, she is is just little padhaku Gunjan who needs to be sheltered and protected because she is motherless and timid. Add to that, the fact that in a small town, for a girl to be bookish and intelligent is no big deal, is even looked at with some suspicion and disapproval - girls are brought up to be married, and who will marry a chashme vali ladki who is only interested in books? A recipe for low self-esteem. But inspite of that, she has a core of steel, a strength born of her ideals and convictions, her values of what is right and wrong - maybe a little too idealistic in today's world, but that's her. And her innate kindness and gentleness probably hides the fact that she can be very ziddi in her own quiet way.
So Gunjan's studiousness and intelligence is overshadowed by her timidity and low self-confidence because of her dominating and over-protective sister, added to that, the contrast between her sister's many admirers, and her none - which is really what counts in a small town, not the number of school trophies she gets. Her strength comes from the love she has got from her sister and father, but her timidity comes from the fact that she is the baby of the house and has never been allowed to grow up and face any difficult situation on her own. Till a whirlwind called Samrat blows into her life and forces her into them.
