The given Twitter post does not seem to be related to a maintenance report feedback for a public flat house. The phrase "behind every storm always rainbow" suggests a positive and optimistic outlook, and the mention of "fernvale" could be a location or a person's name, but it does not contain any information related to maintenance or public housing. Therefore, the answer is a JSON object with "relatedness" set to False, "type" set to "none", and "explanation" set to a brief explanation of why the post is not related to the requested topic.
