Can Shinji get more flustered? Just from hearing that? Yes, he can. But it's fine, because Kai's being so good about all of this, there's no reason to feel too thoroughly embarrassed about it, especially if he focuses more on that warm feeling brewing in his chest.

"Y-yeah." He, too, will keep this offer in mind. With that, he settles back in to rest his head against Kai's shoulder in a more restful, comfortable manner. This... this is good. This has all been very good, all things considered. "And, I can do the same for you."
