I really liked the image of him just missing the first guy and shattering all the windows.

He might be a prodigy, but he's not a very smart one. After the gloomy kid called him out on admitting to things that only the special caste of martial artists would know, and here he does it again like a moron. He'd do a much better job at staying out of the limelight like his master was pretty good at if he would just keep his mouth shut or ask questions by giving less information when he says them. Asking, "Who are you people? You don't look like [teachers/government/etc]" instead of "Are you martial artists?" would be a good start.

Nice scene between the Master and Shiho too.

I wonder how far they're going to develop a relationship with Saehee before Sosul comes back. Saehee is fine, but I have to admit, I'm rather fond of that particular loli-tsundere relationship over the knight-princess style one Shioon has been developing with Saehee.
