While taking over a shift for someone else, Ayaka mistakes Hiroko’s sister as a rival for her affection. That night, Ayaka decides to go all out in her quest to become real lovers.

Ayaka becomes more certain of her feelings for Hiroko, and decides to take advantage of a full moon to enact her plan. She rents a deluxe sweet and sets up a romantic atmosphere, and confesses to Hiroko that she wants to become intimate.

Ayaka looks forward to getting closer with Hiroko, but Hiroko suddenly pulls away and maintains distance, instead turning to help from her fellow lesbians at her local haunt. Unexpectedly, a legendary girl appears and offers her advice.

Hiroko apologizes to Ayaka for getting drunk, but Ayaka is unexpectedly calm, which makes Hiroko even more uneasy, worrying that Ayaka is hiding something. Ayaka, on the other hand, is trying to suppress her emotions and try to become more mature and a good girlfriend.

Hiroko decides to go after Ayaka, who left home due to a misunderstanding. Amid arguments and heartfelt confessions, they finally reconcile. That night, they also gather the courage to begin their 'plan of attack.'
