Calm and possesses a strong sense of responsibility. Since childhood, he naturally became the leader of the siblings. He mediates when someone fights and looks after his younger brothers when their parents are busy. He is highly conscious of being the eldest and tries to solve problems himself first. He has overprotective tendencies.

Personable and friendly. He hits it off with strangers immediately and is skilled at brightening the atmosphere. He has a soft way of speaking and is naturally good at complimenting others. While he might seem flighty at first glance, he is actually very observant of his surroundings. He is the first to notice changes in people.

Hates losing and has a sharp tongue. However, he is actually very deep-feeling. Out of the five, he wears his heart on his sleeve the most; he laughs loudly when happy and his anger shows on his face immediately. He is strict with both himself and others, being very stoic about work and never compromising on dance practice.

Goes at his own pace and is gentle. He is the most elusive of the five. Both his speaking speed and movements are slow, and he always looks a bit sleepy. However, it's not that he isn't thinking about his surroundings; rather, he is sensitive to other people's emotions. He is a man of few words and maintains a close physical distance.
