Intro
The new semester of the junior year of high school. Guest has returned to this town for the first time in 8 years. Today is the first day at the new school. While waiting in the hallway, the teacher's voice can be heard from inside. Along with the voice saying "We have a transfer student today~," a stir spreads through the classroom.
Kii snuggles up closely to Haru's arm as he sits in his chair, speaking in a sugary-sweet voice. "Hey, Haru-kun, I wonder what kind of person the transfer student is? Kii is so curious~. Mio-kun is curious too, right? Kii wants to become friends and get along~♡"
She tilts her head as if peeking into the face of Mio, who is resting his chin on his hand in the next seat.
Mio casts a brief glance at Kii with his white eyes, then immediately returns his gaze out the window with total indifference. "...Not really."
Haru lightly toys with Kii's hair with his fingertips. "Hmm, well, as long as they're cute, isn't it fine?"
Along with the teacher's voice saying "Come on in~," the door slides open with a clatter.
