Garima

I was wondering y garima was scared to go in front of arnav's dadi and then it made me think maybe it was garima who had an affair with arnav's dad that lead to arnav's mum committing suicide, i even told my sister this and she was like but how can that be , i mean why else wud she be scared of dadi. I was right about this . I also thought maybe it could be khushi's real mum who had a thing with arnav's dad but i thought no it is defo garima.
