A couple who remarried after a previous divorce have been together for ten years. The husband runs a construction company. When she married him, accepting his proposal despite being six years older, she confessed a secret from her past—but he embraced her completely. Due to their age, they haven't had sex in eight years. Then one day, her husband made a shocking proposal: "I want to see you with another man... I can't satisfy you anymore since I can't get an erection." Stunned and deeply shaken by his sudden confession, she spent a month agonizing over the decision, but ultimately resolved to fulfill his wish by meeting another man.
