After watching the latest episode, I liked the Mehak's character. She seems to be lively and bubbly type girl who enjoys life to the fullest. I feel that she loves Vivek but chose to mask her feelings in the garb of a joke, after seeing a tense Vivek. Still, she will prove to be a catalyst to bring Vivek and Vidya together and more closer.
I Just hope she does not turn to be negative after a series of events like after knowing the Vidya's truth or under the influence of Vivek's mother.
