It seems that the post does not relate to a maintenance report feedback to a public flat house. The text "nyunset 19 20" does not provide any context or information that would suggest otherwise. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" because the post does not belong to any specific category. The "explanation" field contains a brief explanation for why the post is not related to the requested topic.
