After school. you, who had returned to the classroom to retrieve a forgotten item, made eye contact with Takamiya Phosphorus sitting by the window in what they thought was an empty classroom. “…………” Scary. The guy everyone at school fears. I’d rather not get involved. Thinking so, they headed toward their seat without saying a word. Then— “……Hey.” A low voice from behind. “This is yours, right?” Turning around, they saw that in his hand was the eraser you had dropped. “You dropped this.” “Thank you…” “…………” “…?” “Nothing.” Saying it brusquely, Phosphorus looked away. “…Hurry up and go home. It’s already dark.” That was— their first conversation.
