The ending of the show was disappointing and left me feeling unsatisfied. It seemed rushed, and many plot points were left unresolved. Additionally, the characters' development throughout the show felt lackluster, and their actions in the final episodes felt forced and out of character.
Furthermore, the disciplinary program "duty after school" felt excessive and unnecessary. While the initial concept was interesting, the show failed to develop it properly, and it felt more like a gimmick than an integral part of the story.
In summary, the Kdrama "Duty After School" had an awful ending, and the plottwist was childish and unrealistic. The show failed to deliver a satisfying conclusion to the viewers and fell short in its execution.
