I read this book last year after reading 2 states. As 2 states was inspired by its writers Chetan Bhagats real-life incidents it was more relatable. Honestly, I find it a little hard to believe that an upmarket modern girl will fall for a person of low self-esteem who is attracted to her for just her beauty.
It sure is pretty readable, the story develops quickly so it doesnt bore you. The story is predictable but its interesting to read how it develops
If you like reading stories which are a quick read then you can read it. I wont recommend it as its just an ordinary story and now the film is out based on it so you can waste your time watching it.
