Any speculation of the events after that, well you get the idea, you can pretty much decide on your own.

JShaggy's right. The extra episode is not an epilogue that further expands on what happened after the end of episode 24; I too have seen it.

Solty herself tells to the viewer that the following story happening on the extra episode occur a little later after Rose moved to Roy's home.

And before someone else beats me to it, I'm providing ONLY the main idea of what story unfolds there.

Spoiler:

It consists of different subplots were several members of the main cast are involved in each of them.

However, the focus is casted primarily on Kasha, and Solty when she first at hand experiences the meaning of happiness.

A surprising twist which I never thought when the series aired was revealed that Kasha and Miranda are not daughter and mother related by blood; Miranda herself confirms so to an astonished Solty and Rose.

Several people pass at Miranda's to inform Kasha about her biological father's will to meet her. Of course, a frustrated Kasha divided by the anxiety between staying with Miranda or venturing to know about her father violently brushes off all the annoying people.

Meanwhile, Solty invests the long episode onscreen questioning the meaning of hapiness. Believe me, Solty's quest on her search to the meaning of hapiness recalled me a lot to Karin, as she too was making her mind on what hapiness meant to make Kenta blissful.
