This is was one of my og manhwas, and boy, was it a good one. I absolutely love the mc, she's so amazing and stubborn, and she even has understandable flaws that don't just boil down to being oblivious, too kind, or too strong as you'd expect from these types of stories. The world building and lore about the spirits is really interesting, it really feels like a huge achievement whenever she gets one.
The only bad thing I have to say about this is that it sadly got cancelled
Cale is an absolute gem to read about considering how nonchalant yet cunning he is and he's also tsundere. The side characters are just as fleshed out as the main cast even the villains aren't one note. The Great and Mighty Raon Miru exists so it's an easy S for that alone. It also has no romance and is purely found family centered
I'd recommend the novel over the manhwa tho it has better pacing, more character interactions, and the manhwa changed some pivotal plot points
Iruma is everything that is good and pure in this godforsaken world. This has such a large and varied cast of characters who could honestly each have their own spin off manga. The plot is slow since it's more focused on slice of life but the world building is really nice and there from the get go the art also helps subtly establish it. This and ass class almost made me respect teachers.
I do wish it touched on the abuse and neglect Iruma suffered more tho
