Every night, a wounded man walks into the hospital.
By morning, he vanishes without a trace.
Luchen lives a double life—cold and disciplined by day, a ruthless Alpha wolf vigilante by night. He hunts criminals the law failed to punish, returning to the hospital only when his injuries become impossible to ignore.
Xuyan, a short-tempered night-shift nurse, dislikes reckless patients like Luchen. Yet no matter how angry he gets , Xuyan is always the one who stays—treating Luchen's wounds, watching over him until dawn, and worrying long after he disappears.
Neither of them knows the truth.
Luchen doesn't know that the human nurse who challenges him every night is his fated mate.
Xuyan doesn't know that the man he claims to hate is bound to him by instinct and fate.
As the nights grow darker and the full moon approaches, secrets begin to surface. Between anger and silence, duty and desire, both men are forced to face a truth that could either save them—or tear them apart.
Under the same moon, two hearts are already connected…
even before they realize it.
