Keiki flatly turns down Sayuki’s request that he make her his pet—he’s just not sure if he’s into S&M, and probably never thought about it. But that doesn’t stop her from hanging around him, even in the library, where she gets too close and draws the ire of their mutual kohai, Koga Yuika. When Keiki admits he took Sayuki out for a parfait and performed a romantic wall slam, she’s angry, but he can cure that anger by taking her on a date.
Keiki does everything right thanks to some pointers from his little sister Mizuha: Arrive early, compliment often, go to a movie she likes, have a relaxed lunch, match her pace, let her shop till she drops. He even has the opportunity to rescue her from some leering mall trolls. Yuika gives Keiki a pat and kiss on the head as thanks and then falls asleep on his shoulder on the train home. All in all, it’s a wonderful first date for the both of them.
Yuika always kept to herself in the library and was hard to approach (which he chalks up to her mixed heritage, which…okaaay), but he was persistent in his friendliness and kindness, and her suspicion and “ice in her eyes” gradually melted away to the point they’re now much closer. But is she “Cinderella” who included a pair of underwear with her love letter? The jury’s still out.
What becomes painfully clear, however, is that Yuika is not like Sayuki, and she does not want to be his pet. In fact, when she asks him to meet her in the library storage room, she reveals that she wants to be his master, and wants him to be her slave. As an incentive, she removes her underwear and offers them to him. When he doesn’t immediately take them, she punishes him by stuffing them into his mouth. Yikes!
Suffice it to say, this development comes as something of a shock to Keiki. He was so enchanted by their conventional date, he would have been content if he died the next day. Instead, he finds himself passed out in a closet with Yuika’s underwear in his mouth, and a commando Yuika sitting astride him. They’re tricky, those tides of fortune!
