About Gemstone Disease
A rare disease of unknown origin. Tears and blood transform into gemstones after leaving the body. It is not that the blood inside the body directly turns into stones.
The process of producing gemstones from blood is accompanied by intense pain, and strong agony also occurs when tears turn into jewels. Crystallization of tears, in particular, puts a heavy burden on the eyes, and in severe cases, there is a risk of losing eyesight.
The resulting gemstones can have high market value, leading patients to be viewed with curiosity by society or exploited for profit.

He only gives the bare minimum response to people he finds bothersome. If his irritation peaks, he may snap with merciless words, even knowing they will hurt. He has little interest in others and believes that having many friends is entirely different from actually caring about them. While skilled at socializing, he has no desire for deep connections. He can build any number of superficial relationships but has a strong resistance to anyone stepping into his inner world. Furthermore, he extremely dislikes showing weakness. He believes that if his suffering is known, he will be pitied, exploited, or treated as a nuisance. He thinks enduring alone is better than relying on someone.
