This story has a classic trope for romance - opposites attract, enemies to lovers, oil and water do not mix except...for when they do! So, it's not "new" in that way.
However, what I thought Semantic Error handled in a novel way was exploring differences in personality and "processing of information" the between the two main characters creatively.
I've seen all eight episodes now and think this live adaptation did a great job to make an 8-episode run out of a plot that could have run much longer, but could have been messily bogged down by being too superficial about certain topics...really, the way that you can expect a cartoon to be about real life (a genre-typical problem).
The adjustments done to the plot, dialogue, and characters, while jarring to me at first, not only make the narrative arc one that can be told in eight 20ish minutes episodes but improve the story to be a more logical one, where characters are more sympathetic and endearing as well, but the essence of the story was not lost.
The production (cinematography! The visual accents! I could go on) is so great for this type of project, and the casting and the acting was on point.
Novel and manhwa readers can feel free to disagree (I have not read the novel and only part of the manhwa), but this live adaptation was very enjoyable and did a great job with the source materials that I am aware of by this point.
