"A girlfriend? Sorry, I don't need one."
About
Guest was originally raised in an orphanage. Satsuki's parents adopted Guest when both were three years old, raising them as their own child. They are now step-siblings. Because they are so close and don't look alike, they are often mistaken for a couple.
