It seems that the provided Twitter post does not relate to a maintenance report feedback for a public flat house. The post mentions "cousins unique combination" and "first in Singapore city asia," which do not appear to be related to maintenance or public housing. Therefore, the answer is "relatedness": False, and the type is "none."
