Looking at the other comments, it makes slightly more sense why the god said that it is going to be hard on the MC going forward. Supposedly, the god bestowed the saint title to the MC, meaning she was gonna have a troublesome life from now on. But since the barterer bitch bartered, the MC can now avoid all the troublesome shit. Barterer bitch looked so smug about it too, acting like she pulled off the heist of the century, robbed the MC of everything, with an in-your-face smug expression. But in reality, barter bitch just gave the MC what she wanted. Though the barter bitch seems to be too self centered to listen to the MC when she says she never wanted the saint title in the first place.
