In Ancient Greece, the concept of love could be derived into eight different forms: eros, philia, agape, storge, mania, ludus, pragma, and philautia (you can look up online what each of those individually mean). All of these are viable options that can be explored throughout the roleplay, and we don’t even need to focus on just one of them, since love can change overtime. It’s more about on the connection between the two characters and how it develops over the course of the story, whether it be romantic, platonic, familial, or something else.
