Often, they end with a sense of melancholy. The person with unrequired love may have to accept the reality and move on. For example, in 'The Great Gatsby', Gatsby's unrequired love for Daisy leads to his tragic death and in a way, his unrequited love ends with his own destruction.
Some end with the unrequired love becoming mutual. For example, in many contemporary romance novels, the two characters finally realize their feelings for each other and get together.
In unrequired love novels, there are usually strong emotions. The one with unrequired love may go through self - discovery. In 'Jane Eyre', Jane has to come to terms with her unrequired love for Mr. Rochester and in the process, she discovers more about herself and what she truly wants in life. Also, there can be a lot of inner turmoil and conflict within the characters.
A good example of an unrequired love novel is 'Wuthering Heights'. Heathcliff's intense love for Catherine seems unrequired at times, especially as she marries another. 'Anna Karenina' also has unrequired love themes. Anna's love for Vronsky is not fully reciprocated in the way she desires, leading to her tragic end. 'Lolita' can be considered in this category too, where Humbert Humbert's 'love' for Lolita is a very complex and unrequired form, though this novel is also controversial.
Sure. 'Pride and Prejudice' can be considered as one. Elizabeth initially has unrequired love towards Mr. Darcy due to misunderstandings. Another one is 'Jane Eyre', where Jane has unrequired feelings for Mr. Rochester at the start as she is just a governess and he is her employer. And 'Wuthering Heights' also has elements of unrequired love between Heathcliff and Cathy.
A great example is 'Twilight'. Bella's love for Edward was kind of unrequired at first as he was trying to keep his distance due to his vampire nature. Also, 'Wuthering Heights' has elements of unrequired love. Cathy and Heathcliff have a complex relationship where their love is not straightforward and often seems unrequired at different points in the story.
Unrequired love manga often features intense emotions, one-sided longing, and the struggle of the character to deal with unreciprocated feelings.
Often, revenge love novels end with either forgiveness or a form of reconciliation. The characters who were seeking revenge realize that love is more important than holding grudges. For example, in some novels, the person who was wronged may forgive their lover who once betrayed them and they start anew.
Many dramatic love novels end with a sense of resolution. Take 'Jane Eyre' for instance. After going through a series of trials, Jane and Mr. Rochester are reunited and start a new life together. However, this doesn't mean that all the problems are gone. But it gives a feeling that love has prevailed in the end. There are also those that end with the lovers parting ways forever, which is a very dramatic way to show the impossibility of their love due to various reasons such as social status or personal beliefs.
Some end happily with the couple getting together. They might decide to stay together after the summer ends, perhaps moving to the same place or making long - distance work. For example, in a story, the two characters who met at a summer resort realize they can't live without each other and make plans for their future together.
Often, they end tragically. For example, in 'Romeo and Juliet', both lovers die. Their families' feud and the forbidden nature of their love lead to this tragic outcome.
