I Read this book on july/16 and I think it is a another great work by chetan bhagat this is the story of a simple and typical bihari boy and a hot shot delhi girl they studied in a same college and fall in love with each other but the intresting part about this relationship is their language to communicate and a word that given by the girl’HALF BF’ means more than friend and less than bf this was the intresting love story and I recommend to read this book more than watching this movie because with reading you touched with this character
