On the one hand, it's nice to see the series lean into its SoL side a little bit more this episode. Taking a departure from karuta and seeing our characters function in school with the looming festival is a nice touch and I think it's beneficial for the series to do this every now and then. On the other hand, I don't think Sumire can command an episode yet. Her romantic drive towards Taichi is still underdeveloped, and given that it's an important part of the OVA, it just doesn't keep my interest. I like her tactics, though - seeing how she wins the othersover to her side is entertaining, and the payoff feels on brand for this series, even if it's not the most fulfilling way to end it.
