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. It is unclear who "빈아" is, but based on the name, it could be a close friend or a romantic partner. The target name "빈" is likely the person the author is addressing in the post. Task 3: I would score the appropriateness of the reply as 2 out of 10. The reply seems to be assuming that the author is expressing their love for the person who wrote the reply, which may not be the case. Additionally, the reply is overly familiar and may come across as insincere or inappropriate. Task 4: Alternative reply: 마카님, 빈아가 어떤 분인지는 모르겠지만, 마음이 따뜻한 글에 감동했습니다. 행복한 일들이 가득하길 빕니다.
