She should choose her mother before TVS, but given Gulabiya's track record in Sugni's eyes these past few weeks, she will choose TVS.
As we all know Sugni is falling more and more for him. And all she is getting from her mother is doubt, suspicion, and a story that he is hiding a secret that is inconsistant, ( one week a child, next week a wife!), yet all Sugni is seeing is a man who loves her, stood up to the world to her , and is treating her like a princess. So blinded by love she will make her choice.
Gulabiys giving her daughter an ultimatum is not going to favor her either, the last thing a teenager wants to hear from her parents, is "it's either me or HIM!"
