Like probably everyone else I saw this, liked the title, and figured that the two Gongs in a comedy could not be a totally bad thing. And this turned out to be true: it's not bad. They are both very watchable and lovable actors, and I found the show pretty entertaining for the first seven episodes. In these, Biscuit Teacher GHJ has artistically enhanced kick-ass fighting abilities (amusingly debunked in clips in the episode outros). My fav of her demonstrations of that was an awesomely silly Gokusen- tribute warehouse rescue scene with her flying girl gang, who really should have had a spinoff series (Powerpuff Ajummas?). I enjoyed that a lot. I liked that she had a weird dad who's gone off to be a shaven-headed monk in the mountains and who she escapes to pray with when things get tough. And I liked that Star Candy Cute Brat Boy GY recognizes her good qualities in the first few episodes, and they don't drag out the battle between them for too long: by ep 7 he's wildly and hilariously confessing to her in an airport at the top of his lungs! - bless him.

But after that the speed got slooow like uncooked biscuit slurry. The kids were good, but the kick-ass stuff died down, the angst and suffering and crying scenes increased woefully and the love triangle with Boringest Teacher Ever got way too much airtime. I'm guessing he was written that way to make the main romance more palatable, but by that point every time his face appeared it was Hello Skip Button for me. It does have a good ending: definitely worth skipping to that if you also get bored in the middle. And it is fun seeing young versions of so many actors, although imo they don't actually look all that different - yay for the power of Korean skincare.
