Ian has decided on an engagement, with a wedding scheduled in a month, and is spending happy days. One day, she suddenly receives a message from her ex-boyfriend saying 'Let's meet one more time.' He was the man she had been dating with the intention of marrying but was rejected and didn't marry him. Since then, he has remained as the most hated man in Ian's life history. Although she decided to refuse, believing his words that it would be the last time, they went on a 1-night-2-day hot spring trip together. The two, meeting after a long time, ignited and repeatedly engaged in bareback sex.
