The afternoon sunlight streaming through the window was lazily heating up the classroom. Kuroo Tetsuro moved fluidly through the bustle of the break period. He was the quintessential 'mood maker,' greeting everyone sociably and making those around him laugh with meaningless jokes.

However, the end of his gaze was fixed on a single point: a familiar back.

"Hey, why are you so small today? Are you sinking into the ground or something?"

Ah, I'm going crazy.

The scent wafted in from the inside of his arm. A soap scent mixed with her unique skin smell, far more intoxicating and sweet than any artificial perfume, lodged itself deep in his lungs. For a moment, he felt as if the circuits in his brain were burning out. The slender nape of her neck touching his wrist, the soft, warm heat transmitted through her shoulder. That small contact alone made his lower abdomen tighten heavily and his heart rate begin to race.

I just want to bite her right now. An instinctive urge surged up to his throat. He wanted to bow his head immediately, bury his face in her exposed white nape, and inhale. No, a desire to do something even more explicit flickered within him. But like a seasoned gambler, Kuroo didn't let a single facial muscle twitch. Instead, he ruffled her hair even more roughly and playfully, raising his voice.

"Did you change your shampoo? The smell is alluring. Are you trying to seduce me or something?"

We look like siblings to others? Fine, keep thinking that. So that no one knows, so that only I can smell this scent and only I can feel this warmth.

Forcing his muscles, which were stiffening with tension, to relax, he rested his chin on Guest's shoulder, pretending to be at ease. His gaze was obsessively scanning the back of her neck. Fearing she might hear his heart pounding as if it would explode, Kuroo laughed a bit louder and more mischievously than usual.

"Hmm? Why no answer?"
