Before, it was just Shark's sister, the girl stuck in an eternal coma, somebody else's family tragedy. But now.
Kotori picks out the flowers, thanks the florist.
She isn't used to this.
She has to ask which room, has to double-check which floor, has to find where the elevator is, goes right then has to backtrack and go the other way to find Shark and a body.
Rio's body.
Is it sleeping?
Shark certainly doesn't seem to think of it as dead, but maybe he actually does. Kotori has always had some trouble figuring out what Shark was thinking.
She holds out the bouquet tentatively. It's only an inch from her body when she's told to put it down. Shark doesn't bother to glance over. Good thing, Kotori thinks, she should have asked the florist for advice. Shark would probably think the bright yellow is distasteful and the white looks like death (the ribbon tying the stems together is out of place)
She doesn't know what flowers Rio likes. Does Rio like the color blue? Pink? White?
Her crush is a joke. They weren't really close at all (yet the ribbon is hers)
Kotori wants Shark to leave, comfort Yuuma, doesn't he know Yuuma needs someone right now? That someone is Astral but as much as it hurts, Shark might be able to help more than she or the rest of the Numbers Club ever could.
She wants to tell him to get up and go get Yuuma's kattobing back. It's obvious he can't do anything like that for his sister, so there's no point in him doing nothing but sit in front of her bed. Don't stay here, go make Yuuma smile at someone that's not Astral, even if the smile is still for him.
Then she'd be alone with Rio for once. One more time. Just her and Rio. She doesn't think she needs both hands to keep count of those moments. Just the two of them and machinery again, except this time it isn't a sentient robot. The rhythmic beeping makes it even more obnoxious than Orbital, but she doesn't think she ever wants it to stop.
If Shark leaves, she could be the one who pretends she'll wake up if she waits for her long enough. She could watch the sun set on her white face, watch the warm tones color everything monochrome so she could be deluded into thinking the entire room was the same pure white, gray, just like her sleeping corpse.
(The ribbon's color was faded, it was why she lost her love for it. Now it looks like it was devoid of any color from the very start)
