BLS that are excellent throughout the entire narrative!

Are there any BLs that have a fantastic start? Both the middle section and the conclusion are excellent?

Something I think is similar is "the third ending", "low tide in Twilight" (We all despise Taeju because of the terrible things that he did in the beginning of the story, BUT I'M TALKING ABOUT THE STORY HERE. The story wasn't dull at all; it was fantastic throughout.)
