It seems that the part about winks was lost in translation. To wink - is to close one of your eyes quickly. We often use it to indicate that we are joking. Like this: 😉
You use winks quite often, probably 3 or 4 times in the prologue alone. However, they always look unnatural, probably because you only close the character's eye and when a person winks - you normally should also see changes in facial expression, forehead/eyebrow movement.
