Ahh~, that was cute. >ω< While reading it, I was wishing English had something special like the given-name thing, and then I reached the note at the end and had a little laugh. It's a pity we won't see Seiya-san again anytime soon — I was enjoying the way he was teasing them a bit, and he seems like a fun senpai to have around, maybe even would assist in the secret-keeping. Because wow, but Mitsuya's facade really goes to pieces out of the office. xD Cute, though.
