Is Reyansh and Praniti's relationship toxic in present?
Nope,but it was in the past. Reyansh never intended to have anything serious with her but knocked her up.
I don't think the show is romanticized their past, Did Praniti fall for him BECAUSE he left her?
Nope. Pranati STILL LOVES him.Even after he left her. Even after what she went through because of him. That happens in real life too but it doesn't change the fact that it's toxic.
I am sorry I am unable to understand the POV here
I'm not saying things can't get better with time in the story. TV show hai. Iss liye end tak sab thik ho jayga. Reyansh sudhar jaayga. Jugnu adjust kar legi apni nayi family k saath.But imagine all these things in real life. Tab ye story romantic nahi lagegi. Custody fight,encountering your ex who left you pregnant after so many years,encountering your child who you thought was dead,getting out of an 'almost marriage'. Kisi bhi ladki k liye nightmare se bhi buri experience hogi ye.
Par isi topic ko lightly,in a romcom manner ek TV show mein dikhaya jaa rha hai. And I'm not saying this is a first. Saalo se aisa hi hai TV shows ka. And even I'm guilty of enjoying the show. That was my pov.
