1, Monster tells the story of a woman in her twenties who was killed in downtown Seoul. Tai Shuo, a student of a famous university, was involved in a dispute. If that's what you mean, it's a one-act play. One-act drama is a form of drama, and the whole plot section is completed in one scene. Short in length, simple in plot and compact in structure, it requires the dramatic conflict to unfold rapidly, form a climax and come to an abrupt end. Most of them don't leave the scene or change the scenery.
2. Monster is a Korean thriller movie starring Li Minji. If that's what you mean, then he is a movie.
