A married couple who planned a hot spring trip to celebrate their retired father-in-law. I was a wife who was excited about a family trip after a long time, but I was honestly depressed when my father-in-law asked me to make a child with my wife. It's hard to say no when I'm told it's my reason for living in my old age. Due to such circumstances, I arrived at the inn in frustration, but her wife had no intention of making a child. While spending her sleepless nights, she happened to witness her mother-in-law taking a bath while wandering around the inn.
