Well, if we assume it's a typical love story, the plot might be centered around the concept of waiting in love. Maybe there are two lovers, and one is waiting for the other to fulfill a promise, like waiting for the lover to return from a long journey or to achieve a certain goal before they can be fully together.
Given that we don't have much information on 'love ka hai intezaar', in a general sense, it could follow a pattern where the characters experience love at the beginning. Then something separates them, and the waiting begins. During this time, they might face internal struggles such as doubts about the relationship, and external problems like interference from friends or society. Eventually, they may either reunite and have a happy ending or the waiting might end in heartbreak.
I don't know the plot as I haven't heard of this 'love ka hai intezaar' before.
