la's hug had no passion..no heat...no love...arnav had to hug back without feeling anything...arnav was stiff when he put his hand round la...he didnt even react..and had no expressions on his face Unil he saw kushi's tears...
but if he hugs kushi back there will be lots and lots of passion,heat and most of LOVE in between them...
if he hugs back then it will not be by force...he will hug her back by his own will...as we all can see on the precap there was emotions coming from arnav and this time he did react
