Come On Baka (2017)

Four college mates who aren't particularly studious, eager, or ardent come up with various tactics to avoid being chastised. They have a great life until one of their pals gets into problems and the others decide to avenge him. They come face to face with persons who are outcast from civilised society and represent civilised culture in their pursuit. However, their perception changes quickly, and they now represent the ostracised, working to improve their circumstances.
