From day one of Ta family coming to see charu, it was very much evident that ta was least interested in charu.how come charu family never noticed that.they got a few calls from sudha regarding ta in love with someone else, but still they didnt do the needful.i accept it was charu who convinced them but VR should have been more careful.instead of arranging a professional killer after TT marriage, he should have sought professional detective help in knowing if TA loves someone else. Had they known abt TT love before mrriage things would not have gone this bad. It was on charu-ta engagement that ta left to rescue t from vel for anand. if they knew abt tt by then they would have convinced charu.
Now coming to Charu madam.Charu is insecure and selfish which she hides by being goody goody. First she overtook nitish who is elder to her and the rightful heir. When Ta first met her he was not admiring her rathet he was just looking aroubd the house.charu even adked him "dont you see anything with astonishment". She expected any man coming to see her fall head over heels for her beauty. But Ta was just opposite, her ego was hurt to heal her ego she wants Ta .
