In the city of Herdians, there are two kinds of mages: fire and ice mages. Fire and ice are team-based, and the only way to level up quickly is to participate in a team mission called "Song of Fire and Ice" . The only problem with this mission is that it has no requirements for the number of players. If the two of them were to accept it by themselves, they would not have to fight other players, and they would be able to plan an illegal plan. This is too cool for him, and he's not sure if it's the secret of becoming strong. He's sure that it is, but he doesn't know how to use it. He runs after the thief, who he thinks is a shorthaired female battlemage, and she runs after him, too.
