Synopsis

This is a story of a 29-year-old bachelor who was brought to a different world to live freely. Caught by an "unwanted" wife from day one, his life is not going so smoothly when the entire country focuses its attention on him in ten days. Without losing to such an obstacle(?), he will continue to live on. (Source: Shousetsuka ni Narou, translated)
