Naoto and Chika spend a couple of days completely naked, going at it like monkeys. However, Naoto suddenly finds himself thinking about Ayane. "Oh, I need to go to university and work on my job hunting... and Chika-chan needs to do her final exam review, too..." Chika suddenly flies into a rage. "After taking my virginity, you're saying 'Ayane-nee-chan' is better after all, aren't you!" "Well, that's..." "Just get out!" Naoto finds himself kicked out of his own room. He heads to the university and stops by the career center. He tries to act affectionately toward Ayane as usual, but she seems somewhat distant. Naoto ends up getting kicked out of the career center, too. He wanders the city with his friend Kenta. "What was I supposed to do?" "That's a pretty enviable problem to have." Late at night, Naoto returns to his room. Just then, the door opens to reveal Chika and Ayane standing there. "Which one are you going to choose?!" Naoto wavers, his eyes darting between their breasts. "Is it not okay to say... 'both'?"
