Nayuta and Miyako walk in on Itsuki, who was naked in front of the bathroom mirror, trying to act out the little sister character in his new volume. Itsuki is everything to Nayuta, and Miyako secretly has some feelings for Itsuki, but Nayuta also cherishes Miyako because she showed her compassion in her time of need. Nayuta invites Miyako to the hotel she’s staying at and immediately gets naked. She then asks Miyako to also get naked for some kind of research for her novel...
