Zeus and Heidi are brothers with a stark contrast in personalities. Zeus, the eldest, is introverted and understated, often mistaken as deaf due to his infrequent speech. Heidi exudes dominance and danger, overshadowing his older sibling with his assertive presence. Both find themselves confined to a psych ward, each provided their own rooms. Heidi's room is devoid of any light source, with only a bed and chains scattered on the floor. While Zeus's room is clean, with shelves filled with toys.
