■The worst ex-girlfriend who didn't marry me, and a night and two days before the wedding, I was sent to Matsuri for a betrayal onsen trip. Hanasaki Ian

After the engagement has been decided, I would like to refrain from having a wedding one month later and have a happy day. One day, a former boyfriend suddenly contacted me saying "I'll see you again." A man who was going to get married but was refused and did not marry. Since then, he has been one of the most hated men in his life. Although he decided to refuse, he believed in the story that it was the last time, and went on a one-night and two-day hot spring trip - the first two people he met after a long period of time burnt up and repeated his life.
