Rather than being a fifth wheel, Sayuri clings to Tsurayuki during her extended visit while both Shinoaki and Nanako start clinging to Kyouya, no doubt feeding off Sayuri’s romantic vibes. Sayuri doting on Tsurayuki gives them license to dote on Kyouya. But both we and Kyouya soon learn that Tsurayuki just…doesn’t love Sayuri that way.
When not trying to feed Kyouya, Shinoaki is showing him stills of sex scenes then kneeling between his legs to sketch his crotch. When Nanako emerges from her room whining, Kyouya goes in and assures her the digital music she composed will do just fine, and she “recharges” by hugging him tight from behind, not letting him go.
While Kyouya is being an supportive emotional rock to his dormmates, while Sayuri ups her efforts to return home with Tsurayuki in hand by trying to seduce him in a see-through nightie, Kyouya himself finds support and comfort in his café sessions with Eiko.
She must confess she’s impressed not only by the progress he’s made with the game, but in so easily getting Tsurayuki and Shinoaki to change their styles to something more commercial.
But as the game progresses, Kyouya has a very date-like Christmas Eve out in the city with Shinoaki, and the four make a New Years shrine visit where both Aki and Nanako most certainly hope for more progress with Kyouya. Their implicit trust in his producing abilities is turning into a full-on love triangle, with neither girl prepared to lose to the other.
But, again, as Kyouya makes clear to, who else, Eiko: he doesn’t like either of them that way. And that’s okay! Forget about the fact he’s mentally much older than either. Kyouya didn’t get into this to become either Aki or Nanako’s boyfriend; he did it to remake his life.
Even though this past Eiko doesn’t yet have the history and heartbreak they shared in the future, you can just tell by the way she’s his confidant and emotional rock that these two are the superior couple in the long run.
While Eiko would normally call someone being as wishy-washy as Kyouya a scumbag, she sees why he’s doing it, and it’s not just because he’s scared of hurting them. He’s scared of poisoning the group dynamic and ruining the game they’re working so hard to complete by April 29. Eiko’s advice to him is to continue to feign obliviousness…but considering how bold tAki and Nanako are getting, he probably can’t get away with that much longer.
On top of that love triangle, we have Sayuri continuing to disrupt Tsurayuki’s creative flow, her own goal of returning him to the home and life she believes to be good and right for him clashing not only against Kyouya’s goals, but Tsurayuki’s own dreams.
After Tsurayuki finally blows up at Sayuri and she doesn’t come back, she rolls up in her family’s classy Toyota Century (with its towering, intimidating chauffeur), takes him on a ride to the docks, where Kyouya starts getting unhappy mob vibes. Fortunately, Sayuri isn’t there to threaten him.
However, Sayuri has come to suspect that she’s lost her hold on Tsurayuki due to him being in an emotional and physical relationship with Kyouya. Kyouya denies vociferously, but her suspicions aren’t that out of whack. What she’s wrong about is that Kyouya and the others are leading Tsurayuki down a risky path.
Kyouya maks sure Sayuri understands that Tsurayuki is going down his own path, knew the risks from the start, and is doing it anyway. If she sees Kyouya supporting his friend as he walks that path as unwanted encouragement, fine; but Tsurayuki isn’t being manipulated by anyone. He’s doing what he wants to do, and he’s happy.
Thankfully, Sayuri is a grown-up about this and doesn’t force the issue—though she does leave Kyouya stranded at the docks! She bows and asks Kyouya to continue helping Tsu-kun “find happiness”, which is a heartbreaking thing to hear Tsu’s betrothed to say…but again, Tsurayuki never chose Sayuri, she was chosen for him.
By the same token, Kyouya never chose to be caught between Shinoaki and Nanako, while in their own subtle gradual way he and Eiko seem to be choosing one another. The question is, can he stave off the potentially inevitable destruction-by-drama of his group long enough to finish the game? After that, will Kyouya end up losing both Aki and Nanako after making his feelings clear?
