Tōkan considers then discards the idea of holding Inori's hand. Not yet; give it time.

And soon enough: kitties!!!

They're very cute. And relatable. ...not for being cute, that's not relatable, but for being God's perfect murder machines and not liking most people.

He might actually expire from the cuteness of Inori interacting with cats in a cat café.

"Hi, welcome to Cat Café Mocha Ikebukuro," says a waitress walking over to their table and giving Tōkan a menu (since Inori is over in a corner playing with a cat). "My name is Watanabe. I'll be back shortly to collect your orders!"

"Inori-kun," he calls. "Do you wanna pick something to eat?"

Inori looks a bit annoyed at being interrupted but when he realises the topic is food he immediately abandons the cat to go back to the table and choose. He snatches the menu off Tōkan's hands, looks at the prices, then gives Tōkan an incredulous look.

"Obviously I'm paying, I'm the one who invited you. Get whatever you like."

Well in that case...

Black hole stomach, seriously.

And now back to kitties.

"Have you been to a place like this before?"

"Dunno. Once, years ago, I guess."

"...huh. Why?"

"Haru wanted to come," he shrugs.

"No, I mean, why haven't you come more times since?"

"Dunno."

"Well, we should, then. Maybe visit other cafés, cycle through them so you can taste more food and meet more cats."

...there's an idea.

Yessssss... all according to plan.......

In a few minutes the waitress returns with the family size double strawberry milkshake and two straws. After asking Tōkan if they want to order anything more she walks off, muttering something under her breath about teenage alphas and omegas' unreasonable metabolisms.

Inori notices the milkshake immediately and flops back down onto the cushioned seat across the table from Tōkan. He grabs both straws and pulls the drink closer to him then lowers his mask and starts drinking.

He raises an eyebrow.

...what?

Oh, nothing. He supposes it's his own fault for assuming that the "family size" "double" thing meant Inori would share. 

Is he also a fool for assuming Inori will share the fries?

Yes. Get your own.
