But in reality, Erika is secretly setting up a surprise in Kyouya's apartment and has enlisted Ayumi to keep him occupied. Things don’t go smoothly, though-just outside Kyouya’s place, an unfortunate mishap sends Erika into a panic, leaving Kyouya to figure out how to soothe his eccentric girlfriend.
