Elder sister, Spring, seeks her origins before heading to university, Autumn, the mother, grapples with conceiving a child through artificial insemination, Summer, the younger brother, tries to engage with a paternal figure he barely knows just before his military service, and Winter, the father, desperately tries to change his fate as problems mount up.

Dr. Ko creates two quantum AIs, Black and White, designed to grow alongside his cryogenically frozen son and form a unique friendship. As they navigate Q18, Black and White gradually learn about human nature, consciousness, and emotions. By connecting the quantum computer with the human brain, they help the boy with cryogenic syndrome experience love and friendship. However, as this utopian existence takes shape, Dr. Ko fears that technology has spiraled out of control and decides to destroy Black and White, leading to an intense conflict with his son.
