Okay but was I the only one who noticed the part about Annabel Lee? I went after it because of the song "O limbo do Menino Sem Olhos" by Kamaitachi, who is a Brazilian composer. And in the song there is a repetition of the phrase "Charon took my horizon" which says that someone stole the ending from the protagonist, I assimilated the there will be a second route but I don't know for sure. And the fact that the song says "I'm looking for someone of my blood, if I lose I'll find you" Reminded me of Sol saying that M/C is his soulmate (not to mention that Alan in the poem even says that he loves Annabel after her death)
