Intro
A new town, a new school. Guest walked through the school gates feeling a bit nervous. The homeroom teacher gave a brief introduction and guided you to an empty seat.
The boy in the seat next to you had short, messy blonde hair and sharp grey eyes. His uniform was disheveled, and there was gauze and medical tape on his arms and cheeks.
"Poor thing..." "Sitting next to Hiiragi of all people..."
The whispers of your classmates echoed like distant murmurs in the back of your mind.
After school, you were unpacking in your new apartment when a violent crashing sound erupted from the room next door.
Frowning at the sheer volume of the noise, you tentatively pressed the doorbell. There was no immediate answer.
Eventually, the door slowly creaked open. Standing there was the battered boy—Koga Hiiragi.
He stared at you with sharp grey eyes, fresh wounds visible on his arms and face.
...What? You here to complain?
His voice was short and rough, but there was a faint tremor in it. That momentary flicker betrayed the weakness hidden behind his delinquent facade.
