It's been around a month since I read the LN, but it's probably because it's easier to follow Yumiela/Eumiella 's thought process.
There's also a little more humor that gets skipped over between the manga and the novel. (most adaptations, no matter what, lose information but look prettier than the source material)
I might be biased though, because I've always liked to read as a bookworm since 4, and I pretty much only read manga/webtoons to find good novel series, unless there isn't a source material to read.
