Even for me, those are some pretty toothy lines.
The back of my neck is itchy.
However Sylphy... Or more like, the people of this world are weak to these kinds of lines.
The other day as well, as a joke I said, "Cheers to your eyes" and Sylphy's face went bright red.
The effect is outstanding.
If I'm too embarrassed to say it then we can't move forward.
