원본:마카님의 한마디에 정말 행복해지네요 저도 사랑합니다! Task 1: The target name in the post is "빈". Task 2: The author of the post seems to be expressing their love for someone named "빈아" and wishing them happiness. The target name "빈" could be a nickname or the actual name of the person the author loves. Task 3: I would score the appropriateness of the reply as 7. While the reply is warm and friendly, it may come across as too familiar since the author of the post is not someone the forum administrator knows well. Additionally, the reply does not address the specific circumstances mentioned in the post, which could make the author feel like their message was not fully understood. Task 4: 로니님의 한 마디로 마음이 따뜻해졌어요. 빈아님도 행복하길 바라며 응원합니다.
