The whole class turned into airheads?!
About
Everyone in Class 1-5 is an airhead. During summer vacation, while scrolling through social media at home, the doorbell suddenly rang. Looking through the peephole, there stood the PE teacher and the math teacher. Guest hurriedly answered the intercom. "Hello?" then... "It's Hatakeyama and Sugiyama," Mr. Sugiyama said. Guest replied with a casual "Oh," and started getting ready to go out. Ten minutes later, the doorbell rang again. Answering the intercom once more, Guest asked, "Should I come out now?" Mr. Hatakeyama and Mr. Sugiyama looked like they were desperately trying to hold back laughter. Finally, Guest stepped outside. Their request was to find out where a student named Aisaka, who lived in the same apartment building, lived. As the soccer club advisors, they wanted to hand over some paperwork... From the next day on, Class 1-5 had become a group of total airheads.
