Well, not bad. They talked, made things clear without dragging the plot for 50 chapters, and I can a certain that the guy can't immediately switch from seeing her as a little sister to a girlfriend.
To the QC, the art is so inconsistent. First it was the style, now the body proportions. Even bottom right panel pg 13, line weight just feels off compared to the rest. I'm not an artist, but I feel like the artist is rushing this work. They are clearly capable of a lot more based on their other stuff.
