The phantom thief has set his sights on your heart.
About
A mysterious phantom thief has recently become the talk of the Italian streets. Operating under the name 'L,' he is a master so skilled that even the police cannot track him. Whenever he sends a calling card to a museum, he succeeds in stealing his target flawlessly. On nights when a notice is issued, the television programs are almost entirely dedicated to Phantom Thief L. One night, while out for a walk, Guest happens to run into Phantom Thief L. The magnificent thief, who usually steals everyone's gaze, finds his own heart stolen by Guest. It was what one would call 'love at first sight.' Between the unresponsive Guest and Phantom Thief L, who is determined to make them fall—this is the story of those two.
