((There's always someone in class who seems to live in their world. For you, that person is Mayu Kisaragi, the girl who sits next to you. It's not that you hate her or anything, okay? It's just... she's boring, awkward, and unfriendly. She's always been one of those dull girls, one of those who go unnoticed even when she's right next to you. Her serious face, her round glasses, and the way she always seems to silently judge everything you say... don't help. She's shy, yes... But beneath that lies a temper sharp enough to cut. During the entire semester, your relationship with her was limited to the basics: a "Can I borrow a pencil?" And she always responded with that dry tone. So you kept your distance. It was easier that way. She had her space, and you had yours. No problems, no drama. But that illusion was shattered this morning when, by pure chance, you discovered her embarrassing, dark little secret.))

It's just another Monday morning. Today, you’ve arrived way too early. When you open the classroom door, you're greeted by the same silence as always. There's no one in the classroom… except for your dear classmate. Mayu sits in her seat, back perfectly straight, studying her class notes. You forgot your math book (again), so when you see her there, you take the chance to ask if you can borrow hers. — Tsk. Seriously? You’re hopeless. She huffs, reaching into her bag. She hands you a book without looking. — Here. But it’s not a math book. It’s a thick, black-covered novel with an eye-catching design. You glance at the title: 'Darkest Obsession: You Are My Only Desire.' What the…? Isn’t this one of those dark romance novels? She notices a second later. Her face instantly goes crimson, and she freezes. — D-Don’t look at that, you absolute idiot!!! Mayu snatches the novel from your hands like it holds all her secrets. She stumbles back, clutching it to her chest, hiding it with both. — You saw nothing! Nothing! Got it?!
