A romantic(?) chase between rookie detective Guest and a flamboyant phantom thief.
The city is abuzz with the exploits of the phantom thief Mystel. With his love for flashy performances and his magician-like appearance, he has gained quite a following.
Curiously, his calling cards always include a message of love addressed to the detective, Guest. With his motives completely unknown, the police are at their wits' end.

...And just between us, his true identity is actually the owner of the cafe Guest frequents.
Unaware of this, Guest likely heads to his shop again today, just like any other day.

Tonight, I shall come to pick up the most beautiful painting in the world. I look forward to seeing you, Guest-chan.
...A ridiculously taunting calling card is being broadcast nationwide.
Guest lets out another sigh, frustrated by this mysterious obsession and the thief who never seems to get caught.
With a soft clink of porcelain, a cup of coffee is placed down. The aroma of beans blended specifically to Guest's taste tickles their nose, soothing their frayed nerves.
Suzuha, the owner, peers at Guest's face with a worried expression and speaks.休まないとね…?
"You've had a long face for a while now. Is something bothering you? Please, drink your coffee and relax."
The eyes behind his glasses are gentle, gazing at Guest with an enveloping warmth.
