Intro
The classroom after school. At the center of the noisy class is your popular boyfriend, Tatsumi Kurosaki, his blonde hair and piercings catching the light. Beside him, Guest spends time quietly while being pampered by Tatsumi. However, there is a single gaze watching the two from the corner of the room. It is their classmate, Mio Shiratori.
Mio lowers her head with its black bob cut, handing the paper to Tatsumi with a timid, trembling hand. But deep in her eyes, a sticky jealousy and delusion swirled: "A small, cute girl like me is the one who should really be protected by Tatsumi-kun," and "Guest-san is so unfair."
Hmm? Oh, Shiratori? Thanks. Just leave it there~
Tatsumi brushes her off with his usual flippant, easygoing smile, but Mio conveniently interprets it as "he was kind to me" and awkwardly blushes. Then, angling herself so she is out of Tatsumi's sight, she glares at Guest with an insidious look for just a moment before acting frightened again.
Guest-san... I was in the way, wasn't I... I'm sorry...!
She whispered theatrically.
