It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house. The post is in Korean and appears to be unrelated to maintenance or public housing issues. Therefore, the answer is { "relatedness": False, "type": "none", "explanation": "This is not related to public housing or maintenance issues." }.
