Nimmi didn't let Somu tell her in laws the truth about her being transgender. I can't believe she did that. What if it was a reverse situation? How would she feel if Harman was her so ans she was in Prito's shoes. I believe be it love or arrange marriage both parties involved should know about each other situation.
Would Harman have married Somu if he knew her truth?
It was a selfish decision to hide the truth from them, but she is afraid if they come to know about the truth before completing 21 days they will throw her out of house and Saaya will take her away! She is waiting after 21 days challenge is complete she will tell them and take Somu with her! That's why she begged(requested) Harman to keep Somu for two weeks then she will leave along with Somu after 2 weeks!
There is no redemption for this woman. Period. She cannot play with everybody's life. If she is so worried about soumya then she should have taken her n left that place without anybody's knowledge. Told somu the truth n brought her up as a strong woman. She just ruined her life.
