Brijesh's dad was a very successful businessman, but didn't have a faithful wife. She had an affair with somebody. Brijesh, & Aditi are his kids, but she got pregnant third time from her boyfriend not Brijesh's dad. So Nahar is half brother to Brijesh. after giving birth to nahar, dad murdered her. Then he got bhabho at home to take care of the kids, but soon he started liking bhabho, then bhabho got pregnant with Pia. after that dad commited suicide.
but i think there is still more to it, because i still don't find it that solid to break nahar & saloni marriage. and actually whatever it is, Saloni will be shaken, but she has shown to be an understanding woman, i don't think she'll break her marriage with nahar.
Have your say!!!
let's make a note & see who turns out to be the closest match with the secret when it's actually revealed in saat phere.
