Zhao Yunlan, head of the SID and a BDSM fan, who now has no master will begin his search, but in his immense investigation he meets a man, whom he does not know almost entirely, but thanks to his damn police curiosity he will run into him, more than he wishes. This is a story of the Chinese drama "Guardian". The characters do not belong to me. Top (dominant): Shen Wei. Bottom (submissive): Zhao Yunlan.
