Kaneki looks up when he hears a knock and sees his wife fidgeting like a kid outside. "Touka? What's wrong?"
She doesn't give him a verbal reply, choosing to walk up him instead with her hands behind her back. He raises a brow when she continues to fidget; she only does this when something went wrong. "Wha-"
"Sorry!"
"Eh?"
"I accidentally spilled some coffee on your novels and…" She hesitantly reveals the damp books, the hard cover and sides spotting brown.
Touka knows just how much he treasures his books and can't help but squeeze her eyes close when he opens his mouth, a little afraid of his scolding; he doesn't show his fierce side often but when it surfaces, she'd rather take her chances with the ghoul investigators.
"You didn't burn yourself, did you?"
"Eh?"
Her hands are being flipped and turned, scrutinized thoroughly by her Eyepatch. Even though ghouls have regenerative abilities, he can't help but worry if she got hurt by the caffeine.
His actions makes her feel slightly guilty but overall, Touka feels her body tingling all over at seeing how concerned her husband is.
"I'm fine. But your books-"
"I can always buy them. What matters is you're fine."
Touka turns a little red; they've been together for a long time now but she still isn't used to this caring side of his. But she's also blushing for another reason.
She lets out a small nervous laugh, "Then I suppose you won't get mad if you see the number of books I accidentally destroyed…?"
The caressing stops abruptly and Kaneki looks up, his eyelids twitching with a bad omen. "… How many?"
"In total, 2? … Or maybe, 8." Her words trail off at the end and Kaneki half wonders if ghouls are able to die from a heart attack.
