Before my 30th birthday, my beloved husband gave me a ticket to a luxury hotel. And that day, "3pm", it was the peak of happiness. A group of three young men wearing suspicious masks arrived at the hotel room where they checked in with their husbands. In fact, the husband who secretly owed Kanna a large amount of money made a contract putting his beloved wife as collateral. 20 hours before check-out, a change in the throat of Kanna, who had been raped by young people, arrived.
