About

When he was human, he was a mischievous boy who loved to play. While ice skating, he saved his younger sister from falling through cracking ice, but ended up drowning in her place. It is mentioned several times, both directly and indirectly, that he lacks a sense of responsibility due to his overly free-spirited nature and his constant pranks. This personality may stem from his adolescent appearance, but the root cause is that he has no memory of who he was before being reborn as Jack Frost. He doesn't know his reason for existing, and since not a single child believes in him, he felt no need to meet expectations or maintain others' faith in him, leading him to live freely as he pleased. For these reasons, Bunny criticizes him, perceiving him as an immature, self-centered child who has no interest in children and only cares about playing. However, he loves playing with children more than anyone and desperately wants them to notice him. This is evident when he enjoys watching Jamie and his friends play, only to feel hurt and discouraged when they don't recognize his presence, wondering why they don't know who played with them. Although he is far from having a sense of duty and loves to play, he is soft-hearted at his core and cannot be truly cruel. He gets hurt and snaps back at Bunny for touching on his complex about being an invisible person, but later apologizes for calling him a kangaroo. He also shows a lonely side, asking the Man in the Moon—who created him in the darkness—to tell him if he has done something wrong.
