[Donald's Perspective]
Normally, the couple would get to know each other better to be able to sense each other's emotions more easily. This didn't only happen when the two of them were together. Even if they were far apart, they could sense each other's joy or anger.
Moreover, some people would even activate some special ability. For example, they would teleport within a certain distance and even completely control the other party's body to obtain their five senses.
At the moment, no one knew how this special ability evolved, and not every pair of marked mates could have this ability. According to a few claims, special abilities were probably related to the couple's deep affection for each other, tacit understanding, and physical constitution.
