I've seen grave spelling errors but this one is kinda funny.
As for the story itself... it's really weird. She must have an insanely fragile ego to be triggered by the nobodies that couldn't keep up with her in the first place. How is this supposed to relate to our MC though is the real question. Sure he is being carried but he still pulls his own weight. This is just a waste of space honestly.
Yeah, it's like reading a generic story taken from
TragicBackstories.com, complete with being let go from a party of guaranteed arseholes and shit talkers, but with a stuck-up, self-important, "we gotta get better" mage being the focal point. Whatever problem she has is entirely self-made, and frankly, I have more sympathies for her former party than her, LOL. Imagine coming back from a life-threatening close call, you just want to let out a deep breath and hit the sack, but this snooty teammate of yours won't shut up about "getting better". And this same c*nt with an "overly serious approach" is now stealing from and picking fights with the MC simply because of her ego, and we're supposed to sympathise with her... because? WTF, mangaka?
