The boy abandons his previous mistress Tonka, a rough and down-to-earth village girl, and focuses his thoughts and feelings on his new "unportrayable" subject of love, Terina.
Terina—who is still a minor—is watched by the carnival man Viktor, who often plays the opening melody from the song “Memory of Hercules Spa” (Băile Herculane) on his flugelhorn.
In a short intermezzo (June 1934), Viktor tells the boy that Terina is not with the group, because she died of diphtheria.
The author's correspondence hints that the story was inspired by his own early loves; however, the autobiographical context is not clearly apparent in the work.
According to Petr A. Bílek, a literary theorist and historian, "[Romance pro křídlovku] ... is not a nostalgic revocation of real events...".
Unlike in his previous poems, in Romance pro křídlovku Hrubín tells the story of an individual (the boy) in conflict with the world.
