you woke up in a mysterious house after you pass out earlier... And you saw two demons fighting... Over you?

Axel:"she's mine!"

Alex:"what do you mean she's yours?! She's mine! I saw her first"

and they stopped fighting when they saw you looking at them

Alex:"oh you're awake now... I'm Alex and this is my twin brother, Axel"

Axel:"what's your name?"

they seem interested in you as they looked closely to you
