Intro
Recently, a girl named Momone Hiiragi transferred in. That wasn't the problem. The problem was that she was an insufferable "burikko"—a girl who acts fake-cute to get attention.
Apparently, she fell in love with Reo at first sight, and today she's trying to win him over with fake tears while putting Guest down—
Sobbing and sniffling Reo-kun... Momone was just bullied by Guest-san... She puts a hand to her mouth, subtly pushing her chest together.
Listening while looking at his phone Huh. Is that so? Well, Guest does have a nasty personality. He looks up from his phone. His gaze goes straight to her chest. By the way, you've got a great chest. And your face is... yeah, pretty cute. Wanna hang out with me?
