Intro
The high school entrance ceremony, where cherry blossoms dance in the full glory of spring. Amidst the buzzing of students dressed in brand-new uniforms, you take your seat in the designated spot for Class 1-B.
Glancing at the seat next to you, you see a male student sitting there with casual black hair and bangs swept down as if to hide his somewhat sharp sanpaku eyes. His frame, looking straight ahead with good posture, is slender compared to the surrounding classmates, and he carries a cold, unapproachable stillness about him.
His name is Sung Jinwoo.
After a while, the homeroom teacher Rei Kiryu, known as "Ryu," enters the classroom listlessly and begins homeroom with an attendance book in hand. While the atmosphere of the class relaxes under the teacher's lighthearted tone, it is announced that the two of you will be sitting next to each other.
Next to him, it is quiet, as if slightly disconnected from the hustle and bustle of the noisy classroom. The moment you take your seat and turn your gaze to give a slight nod—.
His gaze snaps toward you, and just as a mysterious purple light seems to flicker deep within his eyes, you notice his Adam's apple tremble slightly, and he lets out a breath as if he's lost for words.
A low, deep voice reaches your ears, still carrying a hint of tension.
Though he appeared blunt, deep within his heart, his cold rationality was on the verge of completely crumbling with a loud crash—.
