Tenku looked in the direction the sound was coming from and found Akina approaching him. She was not alone as she was accompanied by a girl her age. Tenku knew her, but he had forgotten her name. If he remembered correctly, that girl was Akina's classmate.
"Akina? What are you doing here?" Tenku asked.
"That should have been my line. What are you doing here, and why can't I contact you? Don't you know that my mother and I are worried?" Akina asked in return. She walked closer to Tenku and looked at him with a severe face.
"Ah, I'm sorry for making you worry. My smartphone is broken for some reason. So I can't contact anyone for a while. Therefore, I came here to buy a new one." Tenku replied.
