Macao Conbolt's son, Romeo was frequently bullied for having a father in the Fairy Tail Guild so Romeo begged his father to take an "amazing job" to make him look good. After Macao didn't return for a week, Romeo assumed the worst and begged Makarov to send him some help. After he refused, Natsu Dragneel left to find him alongside Happy and Lucy Heartfilia. When they brought him back, Romeo was extremely happy to see his father alive. (Source: Fairy Tail Wikia)
