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.

At school, Rin is concerned that the disobedient Kouki is getting off track and getting a bad reputation. Meanwhile, when a typhoon hits, Kouki and his mom take shelter with Daikichi and Rin at their house.

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...

As the cherry trees are in full blossom, Rin wants to go flower watching, and Kouki's mother prepares a bentou for this purpose. But the weather forecast announced a spring storm, so Rin and Daikichi make good-weather charms.

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".
