bani is simply too perfect. there isn't anyone in the world like her,she is not a realistic character. in my opinion, she tried to be too mahan and she hurt so many ppl becuz of it, yet all that pain jai had to go thru is jusified becuz she was doing it for him. its not jai's fault wat happened in KC, not entirely. bani's INNOCENT little act killed him inside. her KINDESS towards jai shattered him completely. poor girl. she was just trying to do the rite thing. shame she couldn't find any other way to "save" her husband and be mrs. perfect walia.
btw, it takes more than just an innocent mind and values which emphasize living life truthfully and honorably to make up the "plan" that bani did. and all by herself, too! bani rlly IS mahan.
