The Owner of the Healing Therapy Shop Is Ranked 0th in the World

I awakened with a class no one's ever heard of: "Healing Therapy Shop Owner." But… sight, smell, hearing? What am I even supposed to do with stats like that?! If I enter a Gate with this build, I'll be dead in no time! Just as Bitna is agonizing over it, her status window hands her a mysterious item. "A short-term employment contract?" So if I hire a part-timer… they can clear the Gate instead of me? "You can cure mana addiction?" "Yes—if you sign a contract with me." "…Then sign it. With me." With the miracle news that mana addiction can be treated, S-rank applicants just keep pouring in…! "If I'm going to hand you over, I'd rather see the world end." A shop owner who even hires the world's #1 ranker as a part-timer— so what rank is the boss herself?!
