Well, it's likely the engaging characters. The way the two main characters interact in the workplace, with their love - hate relationship, really draws readers in.
One similar book is 'Pride and Prejudice' by Jane Austen. It also features a relationship that starts off with misunderstandings and dislike between the main characters, Elizabeth and Mr. Darcy, much like in 'The Hating Game'. Another is 'You've Got Mail' which has been adapted into a book as well. The two main characters in it have a sort of adversarial relationship at first in their business dealings but then develop romantic feelings for each other.
One book similar to 'The Hating Game: A Novel' could be 'The Kiss Quotient' by Helen Hoang. It also has a romantic relationship at its core, with two main characters who start off in an unusual situation and gradually fall in love. Another is 'Red, White & Royal Blue' which features an enemies - to - lovers story between two characters from different worlds, much like in 'The Hating Game'.
The writing style also plays a big part. It's witty and draws you in right from the start. You can easily picture the scenes and feel the emotions of the characters. It makes you root for them, whether they're at each other's throats or falling head over heels for one another.
It's a great read. The story is full of witty banter between the two main characters. Their relationship starts with intense dislike which gradually turns into love in a really engaging way.
Sure. 'The Love Hypothesis' is a great one. It has the whole academic setting and the two main characters who start with a sort of fake relationship that turns into something more, just like in 'The Hating Game'. Another similar book is 'To All the Boys I've Loved Before'. It has the young love and the initial misunderstandings between the characters which is a bit like what we see in 'The Hating Game'.
