The description of the boy in paragraph 12 suggests a character's special quality is about to be revealed, aligning with a display of cunning or a particular skill.
Based on the provided text fragments, it appears that paragraph 12 is included in the tale where music prevents an attack and reveals a character's identity. Given the context clues, the options regarding a grasshopper turning into a cricket or a boy reading his name on a kimono seem unrelated to the narrative at hand. The texts do not provide evidence for the girl showing off her knowledge of nature either. The most plausible interpretation derived from the text mentioning 'Gil-Dong' and an 'assassins' encounter suggests that the description of the boy is setting up a revelation of a character's cunning and resourcefulness.
Therefore, the description of the boy suggests that a character's cleverness or special ability is about to be revealed, aligning with the option: The boy has a special feeling about this particular girl. This reflects the sudden appearance of Gil-Dong and his surprise intervention, highlighting his unique qualities and the pivotal moment in the narrative where his character takes on a significant role.
