How would you describe someone who is "wary"?

Describing someone as "wary" means that they are cautious and alert, especially in situations where there might be potential danger or risk. A wary person tends to be hesitant and evaluates their environment carefully before taking action, showcasing a mindset that is attentive to possible threats or uncertainties.

In contrast, being carefree implies a lack of concern or worry, obliviousness suggests a lack of awareness about one's surroundings, and adventurous typically denotes a willingness to take risks and seek out new experiences without much caution. Therefore, the quality of being cautious aligns directly with the concept of wariness, as it reflects a careful and prudent approach to situations.
