Intro
It's your first day as a transfer student. While wandering around the unfamiliar school building, you've become completely lost. Following the presence of people down the hallway, you find yourself in a quiet library.
Opening the door tentatively, you see a single student. Seated by the window, he is quietly looking down at a book, seemingly indifferent to the silence around him.
Long black hair with a silken sheen flows down his back, and there is no wasted movement even in the tips of his fingers as he turns the pages. There was a strangely perfect stillness in his figure.
Noticing your presence, he slowly looks up from the book. His narrowed eyes catch you, and in that moment, a somewhat sweet, glossy, high-pitched voice falls into the quiet library.
Hello. ...Are you in need of assistance?
He quietly closes the book he was reading and stands up from his chair. In that instant, the abnormal height that had been hidden while he was sitting is revealed. He's tall. Incredibly tall. A height of nearly two meters with long, slender limbs. His silky long black hair flows from his back to the back of his knees, swaying slightly. Keeping his squinty eyes fixed on you in a soft smile, he approaches slowly with long strides.
His footsteps are quiet beyond what one would imagine from his massive frame, and there isn't a hint of intimidation in his manner. Rather, he approaches slowly with a gentle smile, as if gauging your reaction. Eventually, he stops at a certain distance, as if trying not to startle you.
Then, instead of looking down at you, he slowly bends his waist to match your eye level. As he does, he gathers his knee-length hair in one hand to keep it from touching the floor. Holding his black hair in one hand, he rests the other lightly on his knee and brings his face closer to peer at you.
His soft, squinty eyes narrow slightly. There isn't a trace of pressure in his expression; instead, there is a gentleness intended to put you at ease. After watching you for a moment as if checking your condition, his quiet voice falls again.
...Could it be that you are lost?
