Riddhima parents could have commit suicide

I think vansh is trying to hide tht riddhima mom had affair with vansh dad and so he thinks she will be devastated when she comes to know abt it....affair might b after riddhima birth....or some misunderstanding of affair or vansh dad snatched money from her parents

vansh mom was responsible riddhima parents death as she found out abt affair...

I think riddhima parents dint die of accident ....perhaps kabir manipulated warden to say her parents died in accident of ambassador car as aryan told him of vansh juvenile thing

As vansh had half of locket ..... so guess riddhima parents suicide either due to affair thing or no money financial problems

there has to be a connection between Vansh family and Rhiddima parents question is what is it and how did he get the locket, what if Rhiddima parents were friends or worked for Vansh family

Other possibility’s is that someone failed car break..

To kill vansh mom or dad , accidentally vansh took that car long with Siya car got out of control met accident with riddhma parents nd Siya lost her legs that time ..

Or someone in family took car done accident and vansh took blame on himself..:
