The Twitter post "singapore 7 15pm sunset" does not appear to be related to a maintenance report feedback for a public flat house. The post simply mentions the time of day and the location of Singapore, and does not contain any information about a specific issue or request for maintenance. Therefore, the answer is "relatedness": False, and the type is "none".
