Okay before reacting just hear me out.
What if Sunny's parents got divorced because his mother found out about his father's affair with Pallavi's mom. But then later Sunny's father refused to take up Pallavi's responsibility so she took her away where her best friend ( Siddhesh's mother ) helped in every way.
But maybe Pallavi's mom was somewhere related to Krishna Rao's family and because she ran away for a guy, they killed her hence Pallavi's mom gave up Pallavi to Siddhesh's parents (and they kept Pallavi as their daughter so for Siddhesh she was always his sister) before dying but then sometime later even they died in a car accident after which Siddhesh took up the responsibility.
Now if Krishna Rao is responsible for Pallavi's mom's death and we already know that he's responsibile for Raghav's father and brother's death. We can have a plot where both Raghvi together take revenge on him for destroying their individual families.
Yupp all sorts of tomatoes and eggs are welcomed 😂😂
