Another element might be betrayal. If Casper trusted someone deeply and that person betrayed his trust, it would be a very sad situation. For example, if a friend stole Casper's idea and took credit for it, Casper would be devastated. Also, unrequited love can be a main element. If Casper loved someone who didn't love him back, it would surely make for a sad story.
Well, if we assume Casper is a person, perhaps the 'Casper sad story' could be something like Casper had a big dream. He worked really hard towards it, but due to some unforeseen circumstances like an illness or a family problem, he couldn't achieve it. He had to give up his passion and was left feeling very sad and disappointed in life.

One main element is Casper's friendly nature. It allows him to approach the object of his love without scaring them. Another is the element of the supernatural world they live in. It provides a unique backdrop for their love story.
Loss could be a major element. For example, the loss of a loved one, like in the story of 'The Little Prince' where the fox has to part with the little prince. It's a sad moment that shows the pain of separation.
One element could be unfulfilled dreams. The old man might have always wanted to travel the world but never had the chance due to various reasons. Another is the feeling of being forgotten. Maybe in a big family, the younger generations are too busy with their own lives and neglect the old man. Also, the death of a loved one, like his beloved wife, can make his story extremely sad.
Perhaps the main plot is that a guest arrives at a place full of hope. But then things start to go wrong. Maybe they lose their luggage if it's a travel - related guest story. This would be a very sad situation as they are in a strange place without their belongings.
One key element is the founders' recognition of the problems in the traditional mattress market. Another is their innovation in product design, like the use of special foams. Also, the direct - to - consumer model is a significant part.

After that, they start to communicate more, sharing their stories and feelings. Their relationship develops gradually until they reach a point where they are deeply in love and ready to face any challenges together.
In a 'Casper Dark Story', themes of the unknown and the power of the supernatural are probable. The dark elements suggest that there are forces at work that are not easily understood. Casper may be at the mercy of these forces or trying to gain control over them. There could also be a theme of redemption, if Casper has made mistakes or been involved in dark deeds and is now seeking a way to make amends, or it could be a story of his downfall into further darkness, depending on the direction of the narrative.
Since we don't know the exact 'Casper real story', it's hard to say the main events. But if it's about Casper the Friendly Ghost, one main event could be his discovery of the human world and his attempts to befriend humans despite being a ghost.
