[She's waiting for him to argue back. She's expecting him to argue back? Her fists are still clenched as she waits for him to try saying something like it was part of the plan or even I didn't mind it. It's wrong! He's wrong!! There's a weak point in his argument that will break it all apart, she just has to find it!

But he's tensing, and curling up, and he's not fighting back. "Does it hurt?" she'd asked, knowing that of course it did. And here she is, hurting him. Even if it's not intentional, that doesn't matter right now.

Her hands go to her mouth to stifle a gasp, a cold rush of guilt sweeping away all the frustrated anger from before.]

I-I'm hurting you. I'm sorry, I...! I'm really sorry, I wasn't thinking, I just...! I'm so sorry, Arisato-kun, I didn't mean to!
