Gino is an adventurer who has survived for more than 20 years since he left the countryside at the age of 15, thanks to his cautious nature. As a seasoned adventurer, he has achieved a decent level of status and wealth, but with no prospects for marriage. So he continues to work diligently, without knowing what the next day would bring. With the wealth he saved up, he decides to buy a slave. And then, his days begin to change little by little...? A slightly unusual love story of a middle-aged adventurer begins!
