Is Your Sincerity Based On A Novel?

I've come across a few people wondering if 'Your Sincerity' is based on a novel, and it’s a great question because the title does have that literary vibe to it. From what I’ve gathered, 'Your Sincerity' isn’t directly adapted from a pre-existing novel—it feels more like an original story crafted for its medium, whether that’s a drama, film, or web series. There’s something about the way the characters interact and the emotional depth of the plot that makes it seem like it could’ve sprung from the pages of a book, though. I love how it blends raw, personal moments with bigger themes, almost like a novel would.

That said, I’ve fallen down a rabbit hole trying to find similar novels because the tone of 'Your Sincerity' reminds me of works like 'Normal People' by Sally Rooney or even some of Haruki Murakami’s quieter, more introspective stories. If you’re into the kind of narrative that digs deep into relationships and personal growth, you might enjoy those too. It’s funny how some stories just feel like they belong in multiple formats—books, screens, or even audio dramas. 'Your Sincerity' has that quality, where you can almost imagine it unfolding in different ways depending on how you experience it. I’d love to see a novelization someday, honestly!
