Tanaka naps in class, gets stuck in his gym sweater and makes weird sound in music class.

Tanaka attracts the attention of a possible apprentice, but learning the ways of his listlessness is harder than it looks.

The school president has a secret and Ohta and Tanaka-kun have discovered what it is.

Ohta discovers that Tanaka has a little sister; Shiraishi explores her feelings for Tanaka-kun.

Tanaka gets soaked in the rain and shows up at school the next day with a cold and face mask.
