Chi Su Mu enjoys feeding stray dogs and doing household tasks. He encounters Gu Xue during an episode of Kleine-Levin syndrome. Gu Xue, who is short-tempered but has a tsundere side, brings Chi Su Mu into the "Whale Fall" organization as an emergency member, where he is tasked with stealing a vaccine. Lacking combat experience, Chi Su Mu is trained by Gu Xue and gradually becomes a more capable agent. Upon joining, he learns about the responsibilities of being a "sentinel and guide." Over time, his initial admiration for Gu Xue evolves into a mutual emotional bond.
