Love Happens Only Once... Rest Is Just Life is not a racy novel by an established bestselling author. It has been penned by the young Rochak Bhatnagar while he was a student, and the protagonist of the story reflects the attitude of the book. The story talks about a young boy whose notion of love is just casual. He walks in and out of relationships easily, dating random girls and flirting with anyone around him. And so it goes on, until he finds a particular girl who takes his breath away. He realises that he really loves this girl and his attitude towards love transforms entirely. But will the girl appreciate his change and accept him? Or will she reject him for his past deeds? The question is answered in the remaining part of Love Happens Only Once... Rest Is Just Life, through emotional passages and delicate situations. The book is based on certain real-life and certain fictitious events, according to the author.
