This is a story (with lemons in it) about a person named y/n a powerful person with a dagger for a heart, they have unknown powers that they have to get the hang of or they'll be executed. All the while trying to get to know the meaning of friendshipand love, something a blue haired boy with a hothead may be able to teach her. (pictures and characters aren't mine it's a spin off of the actual show so- yeah)
