We got these characters getting closer and closer.

Yamada plays a "I'm dumb" game but we all know what she wants. To get closer and closer to Kobayashi. It's so obvious she likes him and she showcases it more than ever in this volume. From when they almost sit next to each other, to meeting in a room way to small for both of them, to him being sick and her visiting him, get all cute/fun moments.
