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 when she was wandering around the inn.
