It really is! Thanks a lot!
I remembered in the story that the seme is an author and the uke is a new editor. Seme is rich, owns a building, and is really famous. Seme had a traumatic experience I think. If I remembered it correctly, he once played the piano.
I really can't recall the title of that. I'm looking for it since I there was a sequel of that that I forgot as well.
