I'm pretty at starting series on chapters that don't give away too much information. I came in at chapter 10, skimming through, wondering where the creepiness was, and thought it was some sort of SoL manga, then I got to the end and was like, "What's going on here??" That made me read chapter 11, and reread 10 all the way through and then go back to the beginning. I didn't know why they weren't talking to each other, what kind of relationship they had, or who spread their picture around. Although, I did notice the glasses girl in the background in 10 or 11.
