The language used matters a great deal. Beautiful and descriptive language can bring the love story to life. In 'The Great Gatsby', F. Scott Fitzgerald's use of vivid language to describe Gatsby's love for Daisy makes the story more poignant. Another factor is the exploration of themes. A good love story often delves into themes like sacrifice, loyalty, and self - discovery. In 'Jane Eyre', Jane's journey of self - discovery while in love with Mr. Rochester is an important aspect.
Character development. If the characters in a love story are well - developed, the readers can understand their motives and emotions. For example, in 'Pride and Prejudice', Elizabeth's strong - willed and intelligent character and Darcy's proud yet kind - hearted nature make their love story engaging. Also, a well - written plot is crucial. It should have a proper build - up, conflicts, and resolutions. In 'Romeo and Juliet', the family feud creates a huge conflict for their love.
Authenticity is key. The love story should feel real and relatable. 'The Fault in Our Stars' is a great example. The relationship between Hazel and Augustus feels genuine, with their insecurities and hopes. Additionally, the ability to create an emotional connection with the reader is essential. A well - written love story makes the reader laugh, cry, and feel all the emotions the characters are experiencing, like in 'A Walk to Remember'.
