Hi 🤗
Ok this is totally my point of view 🙂
I dont know why but i genuinely feel like Rohit lied to his family that he dont love Sonakshi. And the reason could none other than the nosy Sulochna aunty (YK's mom). In the whole house only she is the one who can be desperate to tell Raima about Ronakshi's love status. Admit it. She loves masala and issues in people's happy lives. That time everybody was present including her. Rohit may had thought that if he anytime talks early about Sona infront of his family members. The nosiest person may surely inform this Raima after she wakes up and this may surely detoriate her condition. Even Rohit's eyes were not stable at that time. He was acting very lunatically. He is not even the person who will keep mum in his father's cheap comment. Think about it. Everything happens for a reason right.
This could be the reason why he said that he dont love Sonakshi but in reality he lied to balance the situation but may had became grey infront of his family's eyes. I am sure in future when he will reintroduce Sona to his family and they will ask him about last night bitter conversation he may disclose the truth. But still Sulochna aunty didnt kept mum and said it all to Raima which will lead Raima to go missing. Because we all know Sulochna aunty wants - Siyappa !! 👿
