It seems that the Twitter post "yr2k21 run 121 running" does not relate to a maintenance report feedback for a public flat house. The post mentions "yr2k21" and "running", but does not provide any information related to maintenance or public housing. Therefore, the answer is "False" for the "relatedness" field, and the "type" field is set to "none" since it is not related to any specific category. The "explanation" field provides a brief explanation for why the post is not related to the given category.
