Her connection with the book is that she's made a fanfiction of it with the male lead the creator of the "heart app" (I forget his name) likes! And that book is apparently his favorite, so he basically wants her to keep updating her fanfiction, which is why he lets her stick around even though she's a "malfunction" in his creation.
I totally get your points though, it seems to have driven away from the original plot a lot. ╮(￣▽￣)╭
yesss i remember that fanfic thing, but honestly it was only mentioned that one time as an explanation of how the weirdo from the company met sooae, and then she never touched that fanfic again kkfkfkkkk maybe this will be important later in the story, but for now it's an information that's only remembered every once in a while so it always seems off
i don't know what's happening with the author of this manhwa, leaving so many gaps between the chapters…. it's not the first time a chapter starts completely differently from how the previous one ended (there was this one when sooae found out that eunhyuk’a dad had a lover and we never found out how she discovered that except for a single out of context scene that showed her seeing him with another woman)
anyway im really enjoying the love triangle but there are so many things that still confuse me ): even though the bus accident involving sooae and eunhyuk happened, i think her sudden and seemingly random fear of being near him a bit nonsensical. its also so heartbroken for me seeing dohwa being left aside because, between both guys, he's the one who captured my heart ): the thing about sooae having a connection to that book also leaves me quite confused, because????? she doesn't even seem to be doing anything related to the book lol anyway i really like the manhwa but there are so many pieces of information that seem out of context and without proper explanation (but I keep reading and having love filled outbursts due to the romance lol)
