It seems that the Twitter post "mancave singapore" does not relate to a maintenance report feedback to public flat house. It is not clear what the "mancave" refers to, but it is not a term commonly associated with public housing or maintenance issues in Singapore. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not possible to determine the type of issue being referred to. The "explanation" field provides a brief explanation for why the post is not related to the requested topic.
