Do you like constant energy? Need a hand with something? Want to have a pokemon battle? The title of 'friend' does not mean much to Fang in the end - it just mean someone you don't hate, someone you don't have to hurt. So basically anyone or everyone is one of these friend things.

Enemies are the ones you're ordered to hurt. By who? ...doesn't matter now that they have no memory. Fanghua isn't sure who, how or why to hate someone. Ok that's a lie, they hate sticks in the mud, the patronising, the weak. Anyone who doesn't try or even struggle a little against their obstacle or foe.

Romance means things like running on the beach in slow motion, or one of your gets kidnapped and there's an extensive fight scene right? Oooh, what if they're one half of a star crossed lovers pair and they've forgotten?! ...even if Fanghua had their memories, they would still only know the melodramatic romances of movies and comics.

Kid needs a bit of guidance and control in their life, even if said life only has a handful of memories at this point. You're likely to just get your teeth kicked in instead of a useful min-- friend if you're not careful of how you treat Fanghua. It's not so much right and wrong as it is about respect and reason.
