I can technically use the word "denomination" for a species, right? I know it's usually associated with organized religion, but the dictionary is telling me I can. The goal for me is to get the meaning of "species" without using it, well, I might have to use it.
These a gonna be short because writers block but Zombie x Person would be like a held captive kind of thing where the Zombie is being held captive by the person but then the person/zombie falls in love with the zombie/person. Detective x Gangster would be like the detective was investigating a crime the gang did and gangster kidnaps detective but detective falls in love with gangster. Detective x Detective some person found two personal detectives and set them up to investigate each other and they start to fall in love with eachother (I still don't know if these are romantic tropes-). In Gangster Leader x Gangster Leader two rivaling gangs try to talk stuff out the civil way and the leaders get along and become allies and fall in love. Cops kid x Gangster Cop brings kid with them to work and they put a gangster in jail but the kid secretly thinks the gangsters hot and when the gangster is somehow found not guilty they start meeting up and such and fall in love. Horse owner x detective I'm still thinking but maybe they killed a family member/a family member got murdered and they fall for the detective investigating the murder? Shifter x Shifter they both think the other person is a human and when they go into their usual forms they're friends but they're in love with eachother when they're humans (SOmething like that-). Shifter x Person somewhat like the plot of A Whisker Away; Shifter is in love with person from the begining but is afraid to say they love them and turns into animals/person adopts them as a pet and they finally gain the courage to tell them. Vampire x Werewolf ENEMIES TO LOVERS, OH MY- ENEMIES TO LOVERS! Werewolf/Vampire x Person Person enters an abandoned house/national park and finds this beast but the beast is in love and finds a way to get person to love them by either asking a witch to make a love spell/potion or turning them into said form aka Vampire/Werewolf.
