Endless Story,Splendid

The World of the Married BGM ep.6  

"What was the couple? What were the times together, and what was it that drove each other so cruelly? I've had a lot of questions in my head, but I've decided not to ask any more."

The scene where I swore my marriage vows in episode 5 + 6 combined the music of the ending scene that the three people were looking at.
