All three seasons of KRPKAB (specially 1st one) has been revolving about Trust between Dev aNd Sonakshi and them having trust issues after marriage. Except this season, to Me, Dev and Sonakshi's relation has always been on roller coaster ride. Pyar to ho gaya lekin trust jaldi nahi ho paya. It took long for them to reconcile and not to turn blind ears (especially Dev) and trust each other completely. If asked for perfect love story then I don't think they have perfect Love story (season 1 se hi nahi hai). And I have been eagerly waiting kab Neha ko zordar thappad padega.
