On page 5, I'm pretty sure that it should be "Plus, I didn't know" instead of "Plus, you didn't know" since the one saying that line is Takeda.
Edit: further down the same line: "So you probably couldn't" should be "so I probably couldn't."
I'm expecting that someone either the kouhai or the snake guy to watch this situation from a distance and mistake it for a pregnancy, i will loose my mind if that happens xD
