Can you recommend some undying love stories in literature?

I'm not sure if there are a huge number of 'Undying Love Chinese Yuri Visual Novel' specifically with that exact title. However, there are other Chinese yuri - themed visual novels like 'A Summer's End - Hong Kong 1986'. It has a great story that involves love and self - discovery, and while it may not be named 'Undying Love', it still gives a similar feel in terms of exploring relationships.

Another example could be 'Atonement'. While not strictly a political love story in the most direct sense, the events of World War II play a huge role. The love between Robbie and Cecilia is affected by false accusations which are in part related to the social and political climate of the time. Their relationship has to face the harshness of the war and the misunderstandings caused by the class - conscious society.

One hard love story is 'Wuthering Heights' by Emily Bronte. The love between Heathcliff and Catherine is full of passion, but also many obstacles like social class differences and revenge. Their love is so intense that it leads to a cycle of pain and suffering for themselves and those around them.

There's 'The Notebook' which is also an epic love story. It's about a man who reads their love story to his wife with Alzheimer's every day to make her remember. In literature, 'Anna Karenina' by Leo Tolstoy is an epic love story too. The love between Anna and Vronsky is passionate but doomed in the context of the society at that time.

In 'Call Me by Your Name', although it has some beautiful moments, it can also be seen as a tragic gay love story. The relationship between Elio and Oliver is short - lived and filled with the pain of separation. Their summer love is restricted by time and the different paths they have to take in life. It shows the bittersweet nature of gay love in a world that may not always be accepting.

In 'Less' by Andrew Sean Greer, the main character Arthur Less has his own journey of love and self - discovery as a gay man. It's a humorous and touching story that shows different aspects of gay love and life.

The novel 'Tipping the Velvet' by Sarah Waters is also excellent. It tells the story of a young girl, Nan, who falls in love with a male impersonator on stage, Kitty. Their relationship is full of passion and drama, and the story takes the reader through different social classes and settings in Victorian England.

In 'To Kill a Mockingbird', Atticus Finch and his son Jem have a great relationship. Atticus imparts important values to Jem, and Jem looks up to his father with love and respect. It's a story that shows a strong bond between a man and a boy.

The novel 'The Outsiders' has elements of gangster love. The relationships between the characters in the different gangs are complex and there are hints of love and loyalty. Another one is 'The Godfather' book, which delves deeper into the family relationships and the love within the Corleone family's gangster empire. Also, 'The Wire' in book form has some aspects of love stories within the context of the street - level gangsters and the police trying to take them down.

In the novel 'Maurice' by E. M. Forster, the titular character Maurice is a young man who discovers his homosexuality. His love story is complex as he navigates through the society's norms and his own feelings. He has a relationship with another man, and the story delves into the struggles and joys that come with being in love in a time when homosexuality was not widely accepted.
