Ian is living a happy life with her engagement being decided and her wedding coming up in a month. One day, she suddenly gets a call from her ex-boyfriend asking her to meet him again. A man who was dating with the intention of getting married but refused to marry him. Since then, he has gone down in her history as the man she hated the most in her life. Even though I decided to refuse, I believed that it was the last time, so I went on a one-night, two-day hot spring trip.
