The story takes place on February 14 with the harlequin giving Missy his heart, literally, by nailing it to her door. The story follows the unflappable Missy as she tries to discover who gave her this gift, and what she does with it. The merry harlequin follows her the whole time, wondering what this Columbina, as he calls his various loves he has given his heart to, will do with it. True to his classic trickster ways, in the same vein as Puck, he's constantly meddling with other people's lives and causing mischief as he goes, which often get blamed on Pierrot.
The story includes many of the classic characters from the Harlequinade in modern forms. Most obviously is Harlequin and his sought-after love Columbina, who is named Missy in this modern version. Pierrot, the third person in the love triangle, also exists here in full.
The artwork is a mixture of digitally enhanced photographs overlaid with painting. This serves the story very well as the fantastic Harlequin follows and interacts with the sensible Missy in her normal world. The backgrounds are made very drab, compared to the colorful characters which almost vibrate on top of them.
A stage adaptation of this graphic novel has been produced by Metatron's Men (Template:Lang-pl) group made of members of Śląski Klub Fantastyki (Polish: Silesian Science Fiction Club), starring Jakub Ćwiek as the harlequin and Klaudia Heintze as Missy.
