Both ishita and raman are wrong here...imo
Just because ishita asked raman to win shagun's trust doesn't means he will not use his own brain and will blindly follow ishita's instruction to the extent that he has to behave complete opposite to how he used to behave with shagun before his divorce.Raman needs to oppose things and shouldn't give into ishita's jagatmata nature...and should act which he thinks is ethical and morally right.
I dnt think so ki Raman ishita ke kehne par bhi Shagun ki kareeb jayega...In precap Shagun is the one seducing Raman...m sure Raman will not go to shagun close just bcoz Ishita said so
But How can Ishita send Raman close to another women like seriously ...Bulshit
