Agar tum kisi chiz ko dil se chaho to sari kaaynat tumhe oos chiz se milane me lag jaati hain...
This is what happens and happening with RishBala... Forget RK revenge drama, forget Madhu teach lesson mission...forget Sultan... the truth is RK-Madhu loves each other more than anything...although they are not known the fact or they are just sidelining the fact due to any reason...but still their love is true...their feelings for each other are true so whole world...Sultan, Deepali, Sikky...etc etc do things which makes them come more closer and strengthens the bond...knowingly or unknowingly...
And Deepali...she is the main factor in bringing RishBala together earlier and will always be main factor in future too. If anything goes wrong between RishBala...Deepali's act going to reduce the distance between them...
Deepali do things so that she can be benefitted but it goes exactly opposite to her exceptions resulting RishBala closeness.
