Thanks to the photo of him rummaging through her underwear, Keiki is suddenly Yuika’s willing and attentive slave…and Sayuki is hurt to see her master brought so low, especially knowing it’s due to treachery. Still, Yuika manages to maximize her time with him, dressing him up in a butler outfit of her own design, then using him as a porter during a shopping spree.
After shopping, Yuika takes a bath, but screams when she sees a spider, making Keiki come running to her rescue. Yuika sentences him to death for seeing her naked, but quickly softens when, after she steps on his head, his stroking of her head reminds her of her late grandma. After she trips onto her bed, Keiki discovers she stole a pair of his boxers, so just like that, the blackmailing ceases.
As Keiki and Shouma lament another summer without girlfriends (clearly due to their lack of effort and nothing else) the focus shifts to Nanjou Mao, who first uses Keiki as a model for her boyfriend in a shoujo one-shot she’s working on, then proposes he become her “boyfriend” for research purposes…if he’s not dating anyone else.
Considering how strong she comes on and all the blushing, I wouldn’t be surprised if she actually does like him, though like him with his whole Cinderella investigation, or Shouma with his lolicon, she’s simply hiding from the truth; in her case, behind manga-related excuses. After a recharging hug and sniff, Ayano even proposes she and Keiki start dating, but he respectfully declines. As I said, if he doesn’t have a girlfriend this summer, it’s all his stinkin’ fault.
Perhaps, with a photo taken by Koharu on the day he received a love letter from Cinderella, he’ll finally crack the case open and learn which one of the girls in his life gave him her underwear…or if it’s someone new entirely.
