The post does not seem to be related to a maintenance report feedback for a public flat house. The mention of "singapore" and "7 21pm sunset" 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" since the post does not belong to any of the categories mentioned in the question. The "explanation" field is left blank since there is no explanation for why the post is not related to the requested topic.
