Spoiler alert for anyone who has not finished Rin's good ending and does not want to be spoiled.
For those who have done it, Rin's arc ends with Rin in the field and she says "Whats the word for when it feels inside your heart that everything in the world is all right?" I really loved this ending, so far my favorite (haven't finished everyone yet).
But I wondered, "Is there a word for that feeling?" and I would say that there isn't. So with the help of a fellow FJ and KS enthusiast, we came up with a word that means this feeling.
And the word is: Rinruhe (noun) \Rin-roo\: the feeling inside your heart when everything in the world is all right
