Death of a beloved character often makes a cartoon story sad. For example, in some stories, a cute puppy might die, leaving all the other characters and the viewers heartbroken.
There are a lot of sad novels and music. Here are some examples:
1 Moonlight Sonata (Sorrow on the G String)-van Gogh
2 Raindrop-Richard Clayderman
3. Wedding in Dreams-piano piece-John Lennon
4 "Sad Love Song"-Jay Chou
Sofia Rhapsody-Maxim
Farewell-Bandari
The Red Violin-Maxim
8 "City in the Sky"-piano piece-Hayao Miyazaki
9 Pearl Harbor-piano piece-Richard Clayderman
Silent Hill-piano-John Hamilton
These pieces of music could bring sadness to the readers or listeners, immersing them in the world of the novel.
I can't provide the name of the song in the song,"The Confession of Fated Lady", because I'm just a novel reader and can't get the current context information. But if you can provide more information, I can try to help you find the name of the music.
Once there was a sad dog in a cartoon. The dog was left alone in an old house when his family moved away. He waited day after day for them to come back, sitting by the window with a forlorn look. His little tail that used to wag so happily now just hung limply. Every time he heard a car pass by, he hoped it was his family. But as days turned into weeks, his hope started to fade and he became more and more sad.
Loss is a common theme. For example, in 'The Lion King', Simba loses his father, which is a very sad moment. It makes him grow up in a difficult situation and has to face the reality of his father's death.
The movie "Up" has a very sad beginning. Carl and Ellie meet as children, both with a passion for adventure. They grow up, get married, and save up for their dream trip to Paradise Falls. But life keeps getting in the way, and Ellie becomes ill and passes away. Carl is left alone with his memories, which is a very touching and sad part of the otherwise adventurous story.
Loss is a common theme. For example, in "The Fox and the Hound", Tod and Copper's friendship is threatened by the fact that they are supposed to be enemies due to their species. They lose the innocence of their early friendship as they grow up, which is quite sad.
One cartoon sad story could be about a little kitten who got lost. It wandered the big city all alone, with rain pouring down on it. The kitten missed its warm home and its owner terribly. It meowed sadly as it searched for a familiar face or place, but everywhere was strange and cold.
