It was barely passable in the first couple chapters but quickly dropped down to mtl-tier. There are frequent spelling mistakes and what they say loses consistency starting from chapter five-ish. As an example, at a couple points in the second dungeon they refer to it as a white gate, but then the kid says something about it being a "shitty grey gate" or something, I'm paraphrasing because every single line is a forgettable nothing-burger. Which is it actually, grey or white? Idk, I couldn't really follow the thread because I'd gone into bored hyper-scroll at that point.
Ultimately, just another gate-trash copy paste. Doesn't even capitalize on the title. The childhood friend? She's never around and even when she is she's treated like an afterthought. Not that it matters since her character isn't developed enough to miss her when she's gone. Like every character. Save your time.
