It seems that the Twitter post "rockon tokyo" does not relate to a maintenance report feedback to a public flat house. It is not clear what the post is referring to, as it is a simple statement without any context or details. Therefore, I have marked it as "none" in the "relatedness" field and provided a brief explanation in the "explanation" field.
