Synopsis

Caden Wolf lost his wife and partner to the "Guide Killer," who only kills guides. Afterwards, he falls into despair, almost to the point of losing control and going berserk. The Matching Center sends an S-class guide, Jupiter Valerlux, to treat him. Together they investigate the Guide Killer's identity. Caden, who had refused to be guided due to his guilt and sadness over his wife, gradually becomes more dependent on Jupiter every time he receives guidance from him. At the same time, his self-loathing also grows. Meanwhile, Jupiter, who had been guiding Caden purely for fun, gradually begins to feel affection for him...
