Director Statement

This film explores the theme of "the weight of conscience," portraying how deeply guilt can torment a person.
Through the depiction of a family torn between the desire to take responsibility for their wrongdoing and the instinct to protect their child from an unbearable aftermath and lifelong trauma, the story raises questions about the meaning of family as a shared destiny—where burdens must be carried and endured together.
Amidst his guilt and fear, SeeWoo struggles to make the right choice.
His journey goes beyond a mere confession; it becomes a painful process of growth, as he shoulders the "heavy responsibility" required of him as a human being and as a member of his family.
The film follows the characters’ psychological weight with a restrained and persistent gaze, ultimately posing profound questions to the audience about conscience and the bonds of family.
