A tsundere gyaru yuki-onna JK x male teacher story. A combination of attributes I've never seen before.
Nice try, but the execution is kind of... just ok, I guess? Nothing amazing, but I guess I'm no fan of the slapstick-y "anyone she's annoyed with gets frozen solid" gag, that kinda thing will get old fast if this wasn't a oneshot.
With the male lead being as dense as that I also don't really feel the romance here, it's too one-sided for the girl...
