It seems that the Twitter post you provided does not relate to a maintenance report feedback to public flat house in Singapore. The term "belly beast" is likely a colloquialism or slang term that does not have any specific meaning or context in this context. Therefore, I have marked the relatedness as "False" and the type as "none" because there is no clear connection to be made between the post and the specified topic.
