On the night of the Double Sevens Festival, Maiden Kou Reirin is forced to swap bodies with the much hated Shu Keigetsu. However, Reirin rejoices about the fact...?

As a result of the commotion in the inner court, Reirin is ordered by Noble Consort Shu to relocate her room, though this is simply banishment in disguise. Because the new abode is basically an abandoned shed, Leelee the personal court lady for Keigetsu unleashes the frustrations that has been building up within her heart.

It has been four days since the swap. Reirin, who has been banished to a hut in the Shu Palace, devotes herself to farming utilizing Keigetsu's healthy body. Enjoying a freedom where she doesn't trouble anyone, Reirin spends her days feeling fulfilled. Meanwhile, Leelee is provoked by Gayou, a high court lady from the Kin family who suddenly appeared before her, to harass Reirin...

Keigetsu, suffering from a severe fever, controls a flame to seek help from Reirin. Reirin feels heartbroken seeing Keigetsu managing to calm herself down. Reirin suggests the cancellation of the swap, but the request is rejected. For the upcoming Ghost Festival ritual, Reirin presents Leelee with a garment she had sewn just for Leelee. Meanwhile, Leelee feels that something is off from a certain phrase Reirin unintentionally uttered.

To settle the score with Gayou who enticed Leelee into harassment, Reirin takes Leelee in tow and heads to the Ghost Festival ritual. Not flinching that a seat was not prepared for her, Reirin wearing a handmade garment with beautiful embroidery stands dignified in the hall. In due time, the offerings of dances by the Maidens begin. Seika of the Kin clan who is hosting the ritual dances brilliantly...

Reirin finds it suspicious that Seika said there is no one named Gayou in the Kin clan. Just when she was about to ask for details, the Kou clan court lady Tousetsu comes in with a notice that "Reirin's" life is in danger! Reirin wishes to save "Reirin's" life, but Gyoumei refuses the offer, saying he doesn't trust her. However, the empress Kou Kenshuu tells Reirin that nursing will be allowed if she can show her sincerity by drawing the Bow of Warding all night long.
