"...hey, Inori-kun."
They give him understanding looks. Yes, they know.
(Also, Harutsugu looks like he might be about to cry.)
And it is a testament to Kuroji and Harutsugu's trust in Tōkan that they seem satisfied with Tōkan's judgment.
"Anyway... I suppose the warning I wanted to give you is moot." He looks at Tōkan specifically. "You've... clearly given this a lot of thought."
Tōkan smiles and nods. "Yeah, I... I guess it came out by accident, earlier," and he does not need to explain how. "I really like your son. He's... he makes my life brighter and better. He makes me better. I know I'm just a teenager and we've only been together for a short while, but I guess I'm sappy like that. I want... I want to see where this is going, I want to try to make it work, I want—I want him in my life."
"You're saying weird shit again."
And he's blushing hard enough he might be actually emitting light.
(Tōkan's guess here is that it's something like "Didn't you say you loved him the first time we met????" which, well, fair, honestly.)
"Haru may be a grump but we're both really happy," he says. "We—put on a good front, the day we first met you, Tōkan-kun, but we were scared."
"If you were to have broken Inori's heart I would have crushed you like a cockroach 😊," says Harutsugu brightly.
"And it really warms our hearts to see this," he continues, undeterred. "And I know you can't promise anything, you're young, but... it is a big relief that our little troublemaker found someone as sensible as you."
Inori's dads insist on driving them to Tōkan's, explicitly because they're spooked by the fight they had today (even if they won) and would rather feel safe than sorry. Inori thinks this is a pain in the ass but doesn't argue much, and spends the trip quietly playing on his phone.
Also holding Tōkan's hand, which is a very recent development that Tōkan hasn't managed to get over yet.
When they get in the lift up to Tōkan's apartment he asks, "So why'd you want to come over today?"
He's not sure if he'll ever get over how hot it is that Inori just says stuff like that like it's nothing. Or over the underlying assumptions that colour these things he says, how comfortable Inori seems to feel around Tōkan to casually assume their relationship. Which is maybe kinda stupid, that's how couples are meant to be, right, but it contrasts a lot with how nervous Tōkan himself still feels about it all.
Let's just be straight, here, he's terrified of losing Inori and acting like he needs to tiptoe between eggshells to not push him away.
When he puts it like that in his head it sounds really dumb. Inori just... isn't that fragile. If Tōkan does something he dislikes he'll just say so, and he's clearly expecting Tōkan to do the same, so if no complaints are forthcoming then everything's peachy and anxiety is pointless.
"I like you."
