Wo Gao Laoshi!!

Garam is the biggest bully in the worst school in the city, but he’s bored of slacking off and wants to change for the better. Ahnseung is a nerdy transfer student from a prestigious high school hoping to stay invisible until graduation. Like water and oil, the two shouldn’t mix. Yet Garam’s new ambition requires a model student to guide him toward success, and Ahnseung is the perfect match. Can these two extremely different boys reach a mutually beneficial compromise?
