Haru adjusts the snuggle a little bit and reads some more. There's a lot in there, lots of levels of granularity he can drill down on.
"I guess it's sort of funny, sure. I have suggested to myself that - at some point I will get around to reading the, uh, sex parts - and -" snort.
"...oh?" That's a fucking mood whiplash but you know what? He'll fucking take it. He is NOT HAPPY with the thought of Haru witching or anything related ot that and he welcomes the distraction.
"And that... I will have a predictable reaction to this and I could of course kick you out of the room but I could also simply not do that for, I quote, 'speedrunning purposes' -"
"That is certainly a course of action that is available to you." He is still hugging Haru. From behind. His brain can produce images that might make this a more salient fact about this conversation. He will decide whether to do that in a second.
"I assume when I wrote this I knew more than I do now about whether you are cool with speedrunning purposes but what a thing to have written, like -"
"My radiant sun, have any facts about me suggested that I would find helping you 'speedrun' anything but a privilege and a delight?" Yeah okay he is going to start picturing some speedrunning, seems like a thing to do here.
"I could tell you what you'd like, and you then check it against your notebook," he suggests. "Or you could just use me however you want to, as selfishly as you want to, to do only and exactly the things you want to, without having to spare a thought to what I might want or to reciprocate." Those are basically the same thing, after all.
"I was made for you, my radiant sun. Have you gotten to the chocolate-covered crack part yet, in your notes? I was made for you."
"Then you ought to know that I will always be at your service. I am yours, body and soul, to use as you please, forever."
