Kura was certainly a bit too gentle - if only Mirai knew about what he was used to. He smiled a bit at the compliment, too - he didn't seem to be used to them, although he brushed off the slight embarrassment with peppiness. He was glad it was appreciated and not annoying, though!

"Uh, I'd like that, senpai!" Thankful and friendly, more like 'Kura couldn't turn him down if he wanted to'. And he also wasn't quite familiar enough with it happening at all to wonder if his senpai was offering out of a sense of obligation, or something. So, as it was, he figured accepting was an awesome idea!
