This anime is a masterpiece. It's original, beautiful, honest, and gut-wrenching. Please watch it. If you're into yaoi, if you're not, it doesn't matter, it deals with love in its purest form and it's wroth watching.
Anime don't usually make me emotional, and I certainly didn't expect this one to. But from the beautiful music to the moving dialogue, the story moves fluidly through the episodes, separate but they all come together in the end. You won't regret watching it, so just do it.
Warning: Feels, feels everywhere.
