ultimate fundashi

Please help me find something with similar artistic concerns (both stylistically speaking and relating to the thematic relevance of music and art throughout the story) and featuring a difficult relationship between a main couple (if there is any), preferably gay. Something sort of like the Picture of Dorian Gray, too, but ofc more leaning towards No More Eurydice. If you got anything similar but slightly deviating my description, I’m open to it!
