(For clarity, I have only read through chapter 6, but I can't stand reading more.)
I don't understand the current rating for this manhwa. How does it have above 8 stars with such an annoying female main character (FMC) and garbled plot. Is she in the the game? Is she not? The stakes don't feel any bit high, as the FMC is constantly unmoved by anything other than the male antagonist (MA). The moment it has anything to do with the MA, however, she thinks it's not a game and is now life and death for her; I mean, it kind of is, but doesn't feel so. With her constantly calling everyone else "1s and 0s" (as in data of the game), then what is her worry? She is swapping between an unfunny kind of goofiness and borderline panic-attacks. The MA hasn't done anything to the FMC or anyone around her yet.
It's not a story I've see often, with it taking the longest for any change in any character, but I haven't been reeled in yet. This (somewhat) uniqueness to this story (as a pseudo-horror/comedy/romance) doesn't automatically make it a good story.
At least the chapters are long, or maybe they just feel long. Either way, I can't see myself going into chapter 7 and beyond.
