Kavya is taking revenge from Maaheshwaris

After watching tomorrow's preview my guess is that. The guy with burn and Kavya are bro and sis duo. There must have been something that happened with Sanskar's sister and this guy. He was probably obsessed with her and she didn't give him time of the day. There was an accident some where along the way and he burned his hand. So bro and sis united to destroy Maheshwari's happiness. This makes sense to me what do you think guys?
