Emilio Stadford is a young member of Earl Stadford family and he remembers his past life on Earth when he celebrated his 5th birthday. With his knowledge from Earth, he aims to live a free and relaxing life. It's just that, the Stadford family is actually cursed. all of Stadford men are cursed to have tiny penises. Knowing that fact, Emilio, or Milo as his close friend and family call him, decided to go on a journey to find a way to cure the curse or even enlarge his manhood so his dream of having a harem of beautiful women could come true armed with only his modern world knowledge and strong, young body. Little did he know that there was a looming shadow ready to block his path to cure his curse. "I want to cure my junior. Why do you guys keep disturbing me!?" Notes from the author: - I added sexual content tag because it is harem themed so there is a plan for that in the future. I also added the profanity, gore, and traumatizing content tags because it is a middle-aged isekai world with slaves, war, and constant killing as the norm. I don't really know whether this work will really contain any of that so I just preparing for the future. - I am not a native speaker. I have years of experience translating Japanese novels to English but I still haven't figured out these flowery word things so don't expect some literature art from me. I am expecting the reader to correct me/ teach me a lot for this instead.
