Ex-Girlfriend, Show Some Restraint. Don't Knock on My Door in the Middle of the Night

When I read the title, I thought it was about reuniting after a long separation and chasing after my wife, but it turns out that it just started a little bit, and then it was reborn. It felt like another book, and then the time was a little confusing. It seemed to be fast-paced, but it turned out that it had only been a day, and there were still many suspense stories. It was so confusing that I had no interest in reading anymore.
