You know about childhood traumas and you don't want your precious brother to become an axe-murderer or a pedophile, so you turn around and keep your hands to yourself tonight.

LOL. That was really funny. Ahem. Anyway... I'm usually not a fan of 2nd person stories, but it was interesting! I like that you threw in all sorts of plausible ideas too: not thanking Soubi for taking the picture, or not playing with the kid meal toy even though no one was watching. That way, it still felt like Seimei despite saying "You".

Thanks for writing!
