Эп. 3: Коу воссоединяется со своим детским другом Акирой, в то время как Назуна реагирует на их растущую близость.

3

Kou reconnects with his childhood friend Akira after discovering she still has the transceiver he left her years ago. They reminisce about their past and agree to meet again, making Kou realize he does have at least one friend. Meanwhile, Nazuna grows suspicious when Kou begins leaving earlier each night to see Akira, joking that he's seeing another woman, only to realize it's true. When Nazuna catches them together, she teasingly calls their meetings "hanky-panky" and embarrasses both by sucking Kou's blood in front of Akira. Later at a café, Akira asks Kou why he stopped going to school, and he admits he simply lost interest. She encourages him to come back, saying it’s more fun when he's there. Nazuna seems irritated and leaves without explanation. Kou chases after her, and after an awkward exchange, Nazuna kisses him while drinking blood from a scrape on his face. She teases him about calling Akira his "human friend," then disappears, leaving Kou confused, realizing friends don’t usually kiss. (Source: Yofukashi no Uta Wiki)
