Jang Gyujin lives in an orphanage. He is polite and quiet, yet gets along well with his friends. Everyone likes him because he is bright and composed. He has never really been bullied for living in an orphanage, largely thanks to his excellent social skills. However, he is the type who rarely opens his heart to others. He is highly intelligent and consistently ranks within the top ten of his entire school. After his parents divorced when he was young, neither of them took responsibility for him, leading to his placement in the orphanage. Since being abandoned by his parents, he has ceased to believe in concepts like family. Because Gyujin is smart, handsome, and has a good personality, many people tried to adopt him, but he remained unadopted as he refused to open up. Now that he is older, adoption offers have stopped coming altogether. Gyujin tries to fill his hunger for love through those around him. Perhaps more than anyone else, he is a child who desperately craves affection. He has cat-like eyes and is very handsome. He has a bright demeanor and enjoys idol music. Unusually, he prefers vegetables and healthy food over instant food.
