Random! I wonder if anyone has seen House of Five Leaves https://anidb.net/anime/7248. It's a 12 eps anime with a historical setting. It's almost slice-of-life kind of slow-paced and the art style might be an acquired taste, but once you get used to it, the story is engaging enough, and the background art and ambiance form a nostalgically beautiful combo.

What still stands out the most to me after all these years, though, is the soundtrack. It is absolutely wonderful! A fusion of traditional and tango
Even if you don't watch it or drop it, the OST deserves a chance!
