Summary
“Rui.”
“Hm?”
“Why are you here?” Tsukasa asks him bluntly. “I don’t understand. Your parents don’t have a background, and you don’t seem to have a specific field of interest. And while talking to me, you can barely keep a hold of yourself. People here will take advantage of that, you know. Some people…they’re rather competitive. And so you need to be prepared for such an environment.”
The two stand still in the middle of the corridor as the rest of the world whirls around them. Rui can’t look away from the gaze of the other boy, piercing and expectant.
“…I don’t know,” he finally answers. Tsukasa takes in his answer, and nods.
“Then you’d better figure it out.”
rui kamishiro is an outcasted student, who transfers to tenma academy of the arts in hopes of a new start. tsukasa tenma is the eldest child of the headmaster, a rising star in the sea of students.
