One common theme is the fragility of love. In these novels, the relationship is often faced with external or internal challenges that make the love seem more precious yet tenuous.

One well - known 'dying gay romance novel' is 'A Little Life' by Hanya Yanagihara. It's a deeply moving and complex story about four friends, with one central character's life filled with trauma and his relationship with another man being a significant part of the narrative. However, it's also a very heavy and often difficult read due to the intense themes of abuse, self - harm, and more.
Yes, in some fanfictions, Tanjiro is depicted as the reincarnation of Yoriichi.

Tanjiro's fate in the manga is that he ultimately passed away. This event was a significant part of the story's development and had a profound impact on the other characters and the overall plot.
