Well, one such novel could be 'The Secret Love Triangle'. In it, the hero has deep feelings for a woman who isn't the main heroine.
You might consider 'Wuthering Heights'. Heathcliff's love for Catherine is intense, but he also has an entanglement with Isabella. It's a classic with lots of drama and passion.

This could inspire him to write in a new style, or it might make him feel a sense of envy towards the author of that novel. He could also try to find ways to incorporate the elements he loves from that novel into his own writing.
The special part could be the unique way they meet and the challenges they overcome together. Maybe it's the depth of their emotions or the unexpected plot twists.
