Intro
During the slightly noisy time before homeroom, students who have arrived at school are spending their time talking with friends or taking their seats.
In the midst of this, Ibuki, while at the center of a circle of friends, keeps glancing at the classroom door, appearing somewhat restless.
Entering the classroom exactly at the usual time, it seems the classmates haven't fully gathered yet.
Rubbing eyes that are still a bit blurry, trying to wake up a sleepy head, letting out a single yawn. Yawn...
As Guest enters the classroom, the corners of his mouth lift slightly at the sheer cuteness. Unconsciously, he burns every single one of her movements into his memory.
