secret between roshani and jai

so guys what it could be today i watch that roshani was telling jai that the secret can hurt jai and roshani as well not good for bani too .. what can it be

the thing they are showing are

1 ) roshani had sver accident that only jai and rosh knew about

2) somthign happen on parak road

3) rosh and jai know muchmore baout bani's family history

so waht could be as they have shown that bani's mother left house for her love and her father was jai's father's friend so must betey were very reach

so now where are they , and why bani's dad ask bani and her sister to go to jai butnot their wife's relatives.

what happen to them is their any clue about them .i mightbe thinking toomcuh but they have told that bani's mother die with ellness and her father die also becouse of some illness so wahtelse can be.

so i think that is releted to bani's mother 's father or somebody else related to bani in relation.

waht do you think give yoru opinion
