This was a chapter comment but it's more about the series in general:
The way this flows. Words are said and they're re-examined by each character. Not just for dramatic effect but for the emotional impact they have as the story unfolds and the characters experiences change them. It's so rewarding that it's not 'things said by characters' but something more meaningful? It's satisfying and the author-nim deserves all the laurels for writing something so well-thought out and explored. I don't really like school life but this wouldn't work in any other kind of setting quite the same.
