One of the best romcom novels is 'Pride and Prejudice' by Jane Austen. It's a classic that has all the elements of a great romcom - a headstrong heroine, a proud hero, and a story full of misunderstandings and love that eventually blossoms. The witty banter between Elizabeth and Mr. Darcy is iconic.
Well, 'To All the Boys I've Loved Before' is definitely in the list. It has the cute story of Lara Jean and her love letters getting sent out accidentally. 'Attachments' by Rainbow Rowell is also a good one. It's about a guy who reads the emails of two women at work and ends up falling for one of them in a really sweet way. And 'The Rosie Project' is quite unique, with the socially - awkward professor looking for love in a very scientific manner.
