When Virat held his hand,..., jeevika did not tell mannu, give me ur hand , i will help u ...all she said was said she agrees with virat and that Mannu should face the world, here Jeevika trusts Virat more than anyone for Mannu...
by trusting virat, Jeevika almost did the kanyadaan of Maanvi... as in wedding ... she gave away her Mannu to Virat who will protect her kid sister from anyone and everyone,. she let go off her sister from under her wings..and let her lead her life with the man who loves her unconditionally ...
and when Maanvi accepted Virat's hand.. here...now go to next pic...

the faint smile on Jeevika's face, has the sense of happiness for her sister,.. the sense of contentment, relief that there is someone else who takes care of her Mannu. and protects her from everything .,... .. the smile has a sense of trust in Virat's love and care for Mannu .. everything was seen in Jeevika's faint smile...in fact those are the tears of bidaii ..tears of happiness ...
