How was it a prank?? Didn't Shiva himself admitted they did this because Rishita insults Gaura. A prank is a trick played on someone as a joke, but, Shiva Krish from the starting wanted to scare Rishita as a punishment of disrespecting Gaura, they didn't want to make a fool of her, they wanted her to pay the price of Gaura's disrespect. From the starting it was planned as a revenge move from them rather than a simple prank Rishita was traumatized in the first go itself, they enjoyed that and went ahead with it, everytime there was a fight. The girl was literally choking, fainted but Krish chose to runaway to save himself when he heard Dev's voice, ya ofcourse he was sorry for that but he did leave her there. He didn't confessed , he was caught, and that's a big difference. Had he helped Rishita after seeing her condition, owned his mistakes in front of the family, the scenario would have been completely different but he was caught and hence the reaction were different. In the first condition a heartfelt apology would have done wonders, whereas the second condition required punishment . Shiva when confronted by Raavi made Krish a gay just to save themselves and their plan.So, how exactly this is a mere prank, when the character themselves agree that they did it on purpose. Rishita is a brat and self centred person but she doesn't sit and plan to hurt someone, she hurts because that's her nature and upbringing( which is extremely bad). Whereas Shiva-Krish planned to hurt her. Coming to Dhara beating boys, there are many mother's in the world who beat their kids when they do something wrong, yes they are grown up by age, but their prank was very childish, and a child always remain child in mother's eyes.( Though I hated the scene myself because of execution as I hate violence😆) . Gaura want Rishita to feel the love between the brothers not Dev to feel the hatred for Rishita among family. They want Sabka saath Sabka Vikas🤣 so they silences Shiv Krish when they speak against Rishita as it will distance Dev too especially not for the reason that she doesn't respect Gaura.
