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.

It's the first anniversary of Grandpa's death, which means Rin and Daikichi have been living together for about a year now. Daikichi mulls over what he's lost and what he's gained since Rin came into his life...

After visiting a festival, Kouki is still not tired, so Daikichi suggests a little detour on their way home, thus showing Rin, Kouki and Yukari his "secret place".
