Because of a promise, the male protagonist returned to ancient times and became the second time traveler. I thought it was just a simple ancient journey. As a last resort, he could only act as an outsider with mysterious origins and temporarily stay in this ancient world. What he didn't know was that during his lifetime, his late best friend would always say "I have a super good buddy" to everyone he met. After his death, he was known as the man who caused turmoil in the current situation, and many forces were eyeing the latecomer, the male protagonist. So, the male protagonist, who had just lived in ancient times for a short time, came back from an outing one day and saw a stunning woman sitting on the bed, wearing a wedding dress, deep in thought.
