[Murasakibara pauses in surprise, considering that a moment] Did someone? That's stupid. [He tries to decide if he cares that the letter was thrown away or not. On one hand, it's a little bothersome if Himuro ever does something like that to someone who might later confront Murasakibara about his lack of reply. On the other hand, it saves Murasakibara from having to reply in the first place.]

Hmm. If there were sweets and you threw them away too, then I'd be annoyed. [It's true enough, and he goes back to lazily planting kisses against Himuro's neck, pulling at his shirt to expose his shoulder too.

In reality, Himuro doesn't need to confess anything. It was something they just sort of...fell into. A comfortable shift and transition that seemed natural enough that Murasakibara hadn't thought of any 'proper' way to go about acknowledging it.]

You didn't. [That's all he says on it though, pulling away to look down at him, curious if he was going to actually do something with that now]
