The given Twitter post does not seem to be related to a maintenance report feedback for a public flat house. The post mentions "new thumbnail" and "day 2 vlog" which are not related to maintenance issues, and the rest of the post is about enjoying the atmosphere of a BTS concert and good music, which is also not related to maintenance. Therefore, the answer is { "relatedness": False, "type": "none", "explanation": "This post is not related to maintenance report feedback for public flat house." }
