Detective X Killer X Investigation

The story features Rinai, who has recently become entangled with a young man. He is exceptionally well-behaved and gentle, constantly acting affectionately around her. Despite his seemingly innocent appearance, he proves to be an invaluable asset during investigations, possessing outstanding abilities and acting as her equivalent of Watson.

Rinai herself is quite fond of him but hasn't agreed to a relationship. Her reasoning is simple: she's not interested in pursuing someone too young. Furthermore, nearing thirty, she enjoys her daily ritual of health teas, finding younger individuals perhaps too energetic for her lifestyle.

This is a story about an unreliable female detective and a pure-hearted handsome killer. They solve cases while navigating romance.
