The ending of The Most Beautiful Time was not broadcasted because it was an unfinished story and the ending of the story had not been determined yet. The author of the novel may make changes and adjustments during the writing process, so the final ending may be different. In addition, the side story is usually seen as an independent story that may conflict with or differ from the main story. Therefore, when playing the side story, it needed to be coordinated with the main story. This might also cause the ending of the side story to not be determined or not played.
