From Shukla ka adaalat part it is pretty clear that Shukla Rashmi were in a relationship and Shukla was a control freak, maybe stopped her from talking to certain people and questioned her on each and everything which made Rashmi feel suffocated....much like how we see him behaving with Sana now
While Shukla was answering about how he wanted things to end on a good note between him and Rashmi despite knowing that Rashmi is a liar and has blocked hos number, he called her thru Aarti and wanted to remain cordial with her....I am kinda unable to believe this🤔
Also when Rashmi said I am sorry For cutting you off I want to say something on this....this jerk says then I’ll be sorry too then
Rashmi said he used to question me on each and everything I dunno on what basis....Shukla says tumhe nahi pata kis basis pe karta tha.....clearly implies it was maybe an abusive relationship or a relationship where he was being a control freak and trying to dominate and she dumped him for that very reason, not every girl will be a Sana or an Aarti afterall🤔
