One common theme is self - discovery. The transmigrated character often has to figure out who they are in the new world and in the context of their new relationship. For example, in many novels, they might discover new aspects of their personality through their interactions with their love interest.
Redemption is also a theme. Sometimes one of the characters, usually the 'villain' in the story, has a chance at redemption through the love and influence of the transmigrated character. This theme adds depth to the story and the relationship, as they both grow and change together.
One common theme is self - discovery. The transmigrating character often has to figure out who they are in a new world and how they fit in. For example, they might discover new abilities or aspects of their personality. Another theme is the changing of fate.

One common theme is self - discovery. The transmigrated character often has to re - evaluate who they are in a new world and new relationships, especially in a BL context. For example, they might discover new aspects of their sexuality. Another theme is power dynamics. There could be a power struggle or a power imbalance between the two male characters at the start which then evolves over time.
One common theme is identity struggle. Since the character has transmigrated, they often have to figure out who they are in this new world while dealing with their new - found feelings for another male. Another theme is the clash of different time periods' values. For example, modern values might conflict with the more traditional ones in the historical setting.
A common theme is identity discovery. When the character is reincarnated, they often have to figure out who they are in this new world. Also, there's the theme of male - male relationships development. Since it's BL, the relationship between male characters is a key part, like how they go from strangers to having deep emotional bonds. Another theme is the adaptation to a new world, dealing with new magic systems, social hierarchies, etc.
The theme of forbidden love often appears. Since it's BL, in a horror context, the love between the two male characters might be seen as something that goes against the norm in the spooky world they are in. Maybe there are forces trying to keep them apart because of their relationship, which adds an extra layer of drama and horror to the story.
Power dynamics also play a role. There could be a dominant and a submissive character, which adds an extra layer of tension and excitement to the relationship. This can be seen in novels where one character is in a position of authority, like a CEO or a senior in a school, and the other is more inexperienced.
One common theme is the power imbalance. Since vampires are often depicted as more powerful than humans, in a BL context, this can create an interesting dynamic between the two male characters. Another theme is the struggle with identity. The vampire character may be struggling with his vampiric nature while also dealing with his feelings for the other male character.
Power imbalance is a common theme. One character often has more control or influence over the other, which can lead to the 'abusive' nature of the relationship. For example, in some novels, a wealthy or more socially powerful character can manipulate the other.
One common theme is revenge. As I mentioned before, like in 'Rebirth of the Malicious Empress of Military Lineage', the reborn characters often seek revenge on those who made their previous lives miserable.
Survival and hope are also prevalent themes. The war prisoner often has to fight for his survival in a difficult situation, and the relationship with the other character can become a source of hope. In some novels, they rely on each other to get through the tough times in the prison or war - affected area.
