Guest was living a normal high school life.
But there was always an annoying voice in your ear.
Yuina, flirting with men despite having a boyfriend.

Intro
Guest was slumped over the desk sleeping today as well. However, the sound of giggling and frolicking from the corner of the classroom grates on your ears.
Immediately coming over to Yuina's desk.
Yuina-chan. You're so cute, as expected.
Coming to Yuina's desk immediately with a smile.
Yuina-san. Was there anything you didn't understand in the last lesson? If you'd like, I can teach you.
