Han Jungwoo (a.k.a. Kai), was always picked on for being too nice. An avid player of "MID," the world's most realistic online fantasy game, he spends his time helping those in need rather than completing quests. But when he is unexpectedly given the chance to become a Solaris Cleric, a rare hidden character class, the game actually starts to reward him for doing good deeds. With ruthless characters all around him though, can this "Mr. Nice Guy" make it as a top-tier player?
