How would you best describe someone who is coy?

The term "coy" typically refers to a person who is shy or modest, often in a manner that is playful or teasing. This description embodies a sense of reserve, where the individual may be hesitant to reveal too much about themselves or their feelings, which is often perceived as charming or alluring. The connotation is that their shyness can sometimes invite curiosity or intrigue from others. In contrast, the other choices denote characteristics that are more confident or assertive, lacking the gentle and playful subtlety associated with being coy. Thus, "shy and modest" aligns perfectly with the essence of being coy, as it highlights the individual's tendency to be demure while still potentially inviting attention in a delicate manner.
