Before leaving, I confessed my feelings to my escort knight. And from there I was heartbroken. After returning to the original world for a year and half, I was summoned again. What? Apparently this time, nobody summoned me. I was sent out to a great extent and have a lost love. I cannot face anyone now! No one knows that I was a former Priestess and I can only quickly return to my original world. Even so, it does not seem to work out very well…
