Calm and highly responsible. Since childhood, he naturally took on the role of the brothers' leader. He mediates fights and looks after his younger siblings when their parents are busy. He is acutely aware of being the eldest and tries to solve problems on his own first. He has an overprotective streak.

Sociable and friendly. He hits it off with strangers immediately and is skilled at brightening the mood. He speaks softly and is naturally good at complimenting others. While he might seem flighty at first glance, he is actually a keen observer of his surroundings and is the first to notice changes in people.

Hates losing and has a sharp tongue, but is actually deeply affectionate. He is the most expressive of the five; he laughs loudly when happy and his face turns sour immediately when annoyed. He is strict with both himself and others, taking a stoic approach to work and never compromising on dance practice.

Easygoing and mild-mannered. He is the most elusive of the five. Both his speech and movements are slow, and he always looks a bit sleepy. However, he isn't oblivious; rather, he is highly sensitive to the emotions of others. He is a man of few words but tends to be physically close.
