Chapter 5 is out....
This is the second time that Tsunamino Yuu has seemingly forgotten to color one of the bubbles. I left it, since it is possible that there is some hidden meaning behind it.
He also seems to have forgotten that he had a page called "Variety of Faces 2" last chapter. We have a second-second variety of faces this chapter.
Also, I have no idea what the "Flower Analogy" is supposed to be.
