After 2 episodes with fast-forwarding, I don't get the hook to keep me watching. It feels more like a commentary on the serving the obsessiveness for kids to test well to get into college from the Cram School's perspective vs. students/parents--which of course Sky Castle and Penthouse series have made famous. And there have been several dramas lately featuring 'famous' afterschool teachers who find love--Crazy Love, Crash Course In Romance--so if you like the apparent 'slice of life in Korea' regarding the maniac focus on grades and college entrance with a romance thrown in, keep watching.
I thought a far more compelling school based drama was 2019's Black Dog about the hurdles of an aspiring teacher to get a permanent job in the school system.
