In a Giyuu x Shinobu fanfic, the setting and plot can vary widely. Some might be set during the main events of the Demon Slayer universe, with them facing demons together. Others could be more of an alternate universe story, where they meet under different circumstances, like in a modern - day high school AU. The fanfic could also delve into their backstories and how those experiences shape their relationship. For instance, Shinobu's past with her sister could play a role in how she opens up to Giyuu, and vice versa for Giyuu's own traumas.
I would recommend 'Whispers of the Heart' for Giyuu x Shinobu fans. This fanfic focuses on their unspoken understanding. It's full of small moments that build up their relationship, like when Shinobu leaves a small flower on Giyuu's doorstep as a sign of her care. Also, 'Shadows and Sunlight' is worth checking out. It has a great plot that involves them having to go on a secret mission together and how that journey changes their relationship from colleagues to something more intimate.
Many people also like to talk about sad stories. They share their feelings with friends or family, discussing what made the story so sad and how the characters could have had different outcomes. This sharing helps them process their emotions and also creates a sense of connection with others who might have similar reactions.
One common theme is the exploration of their relationship. Given their different personalities in the original work, fanfictions often focus on how they bridge the gap between them, like how Giyuu's stoicism and Shinobu's more cheerful yet calculating nature interact.
Children might react very directly to sad stories. They may start crying easily and might not fully understand the deeper meaning. Teens, on the other hand, could be more likely to internalize the sadness and become moody or withdrawn. Adults may have a more complex reaction. They might analyze the story from different perspectives and use it as a lesson for life.
