If it's going to be like this in later chapters, I can see why it ended with vol3.
At this point the story avoiding yuri route is just so fricking annoying, and I feel like the story shows the heroine as more and more bad guy who bothers MC.
On page 12 the most eye catching is Conia so if I had not seen that note I wouldn't even notice that there are some artifacts left by AI.
And so the plot thickens~!
