Mysterious Girlfriend's Girlfriend
Oka Ayuka walks into her homeroom, she sees Ueno and Tsubaki sitting at their desks talking, then Oka saw her - sitting across from Tsubaki. Her blue hair obscuring her face, giving her a mysterious appearance.
'I bet she's really cute.' Oka thought to herself.
"Hey Oka, you OK?" Ueno Kouhei asked, breaking her reverie.
"Huh, what?" Oka asked.
