The Commotion regarding the Audio Radio Casette

One morning, Aiko receives an airmail. It was a voice message from Rei. The next day, Aiko talks happily at school. Then, Serin came and said, "I came too. That was a week ago..." Aiko is shocked. I don't want to believe it, but I'm inexaciously harassing Rei. Aiko, who doesn't reply, has a radio cassette and clings to a punk. Finally, Aiko gets angry. I can't help it, so I try to hide it, but this is also found out right away. Finally, I chased after Fujinami and Osaki. At that time, Serinu is questioned by Ryo and confesses, "That was a lie." He said he was jealous of Aiko. Aiko, whose suspicion was cleared, was busy recording while immersed in her memories with Ryo.
