Jeremy's grandfather was a servant in the noble's house but due to some unfortunate incident, he lost his position.
Their lives weren't worse and they were still able to live nicely even after that incident.
When Jeremy was born unlike other children he didn't cry at first and his body was quite hard which was horrifying for his family.
Moreover, the newborn calf of two months could break a finger if he clutched properly.
As he grew, his body ached due to pain in his joints.
They felt that he was quite abnormal and decided to look for medics.
After so many twists and turns, a hidden doctor was able to assess his physique and informed his family that he was blessed with a heavenly exoskeleton.
For a mediocre family like them, it was more of a curse than a blessing. So, they decided to keep it secret until he grew up and had enough strength to back himself.
