Whose fault was that

Story of a group of friends set in the marketing department of one of the Corporate Houses. Three female protagonists, all of them exceling in their professional worlds, but are they really happy? Pankaj, a newcomer to the group, quickly becomes a close confidante to all in the group, so and so that he decides to end his married life to spend rest of his time with one of them. Why Kanika, with a rocking career suddenly severe her ties with all of her best friends, after getting married to her beau.... wherein Harshika hates the entire male fraternity and fathoms Arnav, a guy who introduced her to love of her life. Jwot, a chirpy, bubbly dynamo is always eager to help everyone around her, is alone raising two adolescent kids.. Borrowed from some of the true incidents, story narrates the ambitions, lives the pain and shares the happiness of the characters, observing some of the social taboos from close quarters. Why does a relationship fail and what it takes to keep one going? Why a female has to choose between her father, whom she idolises and the guy who idolises her. Why your own abandon you when you need them? A question, that keeps Pankaj guessing and remains unanswered till the very end is actually who was at fault - expectations, society, corporate pressure, career or something else? Could there have been better turn of events?
