Joon-Young Personality Type, MBTI

Joon-Young personality type is ISTJ, which is the most common type of the Jungian cognitive functions. However, he tends to be more independent and to have higher standards than other ISTJs. In school, he had a reputation of being cold, serious, and not particularly sociable. However, he has shown that he excels at being a leader in his groups, such as the ITE students. During the school festival, he was the one who made all the students participate in the games. He also led the student council in their plan to stop the professor from kidnapping the ITE students and their teachers to give him his "ultimate power." They were easily able to defeat the professor and stop him from kidnapping the students and teachers. He also held firm in his determination to find a solution for his brother's illness, and was able to come up with a solution by using his own money to buy a penicillin that would cure his brother's illness, but it turned out that the penicillin would also kill him. He was very upset by this. However, he still continued to search for other means of saving his brother despite knowing that this may mean saving his own life.
