Daikichi finally meets Rin's mother, Masako, and he's shocked by her frankness. When they part, Masako asks Daikichi for a favor, and it's an issue that Daikichi can't avoid, as long as he's going to raise Rin. Daikichi tries to resolve it by having a heart-to-heart conversation with Rin, but he gets an unexpected answer...

Daikichi's cousin, Haruko, runs away from home to Daikichi's house with her daughter Reina in tow. Daikichi can hardly fathom Haruko's determination, but when he does learn her reasons, he's not a little surprised by how strong Haruko has become as a mother. It gets him thinking again about what marriage and family mean.

Daikichi feels helpless when Rin is laid up with stomach flu, so Kouki's mother steps in to give them both a hand.

Daikichi and Rin prepare for Christmas.
