I'm really annoyed by the appearances of that shy normal girl who has a big crush on Ryuji. I know the series is rather compressed, but she always comes off as unnecessary and completely out of place. Maybe it is just the way the series is presented and it is different in the source material, but Ryuji obviously doesn't like her, pay attention to her, or care about her. Her friend needs to realize that.
Her reactions are barely even good for a laugh. Eriko is much better on the overall comedy.
