簡介: The year is 2099. Earth's environment is collapsing, and society worships "rationality above all." Love and intense emotions are deemed dangerous remnants of the past, permitted only in "Emotion Experience Halls," where people can safely simulate them for short periods. Zhou Tianming, a cloned attendant, patrols the hall day after day, until a girl named Gu Yuanqi comes to experience "sadness" and stirs something deep within him. Inspired by her, Zhou Tianming secretly tries an emotion session himself and searches through archives of love, glimpsing fragments of real emotions from across the ages. He soon discovers that he and Gu Yuanqi are the newest samples in a secret experiment. Together, they decide to embark on a long voyage to Mars, where rules may still exist, but this time, they will choose for themselves how to love and how to live.
