Akira decides to ask his friend, Kouhei Ueno, on what he could do to advance his relationship with Mikoto, though none of his advice seems to work on Mikoto. When asked if they really are in a relationship or not, Mikoto takes Akira to an abandoned house. Telling Akira to close his eyes and undressing, Mikoto feeds Akira more of her drool, explaining that their drool is a special bond that allows them to know what they are feeling. The next day, after Akira has a strange dream involving Mikoto, Mikoto drinks some of Akira's drool and somehow manages to recall Akira's dream in great detail.
