Kumagawa's dialogue in this chapter was also especially lulzy.
Spoiler for for chapter 60:
After politely greeting Hitomi (Zen's loli Mom) and telling her that she was his first love....he then asks her to join him on his shipping trip to the bookstore later to help him pick out his porn.
And proceeds to try and screw her. (and I mean in a literal sense you perverts
)
