A dreamlike, beautiful piece of art. Calming and relaxing, I enjoyed it tremendously. In 10 beautiful minutes it delivered a most moving love story between two young men.
(Here comes a potential spoiler, don't read more if you haven't finished watching.)
Since it has an open ending, the meaning of the anime is left to the viewer. Here is my interpretation.
As the space probe falls towards Earth with not enough time to save the life of the pilot, the AI enters his mind with the goal of making his last 10 minutes beautiful and relaxing before he dies. The AI knows the pilot so well that it knows his most cherished secret wish: to find and marry a beautiful young man of his dreams. Knowing this, the AI induces a hypnotic dream about a handsome stranger with whom the pilot has been together for 7 years, deeply in love, without ing those years, and today is their wedding day. With this dream of their wedding day the pilot dies peacefully and happily.
