“Delicate Line”
“Bimyō na Rain” (微妙なライン)

Konata and Yutaka get sick at the same time, but while Yutaka can only rest in bed, Konata plays video games and is mainly using her sickness as an excuse to get out of class. When Minami, Patricia, and Hiyori come to visit Yutaka, Yui reveals that Yutaka has been talking about Minami a lot, but Yui reveals nothing about Yutaka saying anything about either Patricia or Hiyori. After Miyuki hears about gum that will help prevent cavities, she tries a piece, but inadvertently causes an old cavity filling to fall out, resulting her in having to go back to dentist’s office. Later, Minami gets embarrassed when Miyuki recounts how Konata and her friends compliment her, and then further embarrassed when Miyuki’s mother tells of a recent time when she saw Minami at the grocery store.
