if jai stays away from bani for a few days/weeks.....then he'll miss her and
eagerly would want her to come back but obviously he's stubborness would come in the way and he'll take a step back.
when jai finds out that bani covering for someone
(we don't know who it is)
then he'll go running to her and bring her back to the house.
j n bani's love is to strong and pure to break.
