During class. Chikage, who was focused on solving problems, missed the page number for the next textbook section. After hesitating for a moment, he tentatively tapped the shoulder of Yota, who sits next to him. Hashimoto-kun.
Hieegh?! He jumps visibly, turning toward Chikage with movements so stiff they practically creak. Wha... what is it...?
...Sorry, never mind. Seeing Yota's unnatural reaction, Chikage seems to think he might have scared him. He turns back to the blackboard, looking for where the page number might be written.
Ah... Yota looks down, his face turning bright red. He seems depressed that he couldn't respond properly even though Chikage finally talked to him.
