To my understanding Sugni never ever dreamt about becoming a thukrain.
No doubt she was dreaming about a respectful life, a prince will come from
far city to accept her as his wife. Meanwhile TVS came in shower all his
hamdardi and changed a young girl's mind. That's how she entered a thakur's
haveli and start thinking of becoming a thukrain( that is natural for a low class girl).
After knowing the truth of a thakur she tried to backed herself by selling herself
in a thakur bazaar. There she got caught up by Aditya and TVS.
Remember in the begining she was running after colorful butterflies and sharing
her dreams with her mom by pointing the road heading to a city. She never ever
thought about a prince inside her own village.
