we have seen siddhi being jealous pre-leap and it continues post-leap...but post-leap its so cute to see kunal jealous...as pre-leap he never got jealous for either richa or siddhi...he was happy living his own land...now look at him jealousy in love makes him so drunk that he have no sense...he cries...he hurts himself...he looks too cute...
he can't tolerate siddhi with anyone...i think if anand SR would be alive and both is in love with siddhi...though he loves his bro...he might not disclose it and might sacrifice his love for his brother...but he will destroy himself by getting drunk...and that is his style of showing jealousy...whatever kunal does...he does with a style...
