I hated the fact that they gave so much screentime to Charlotte when Silvye was supossed to be the fiancee... Teppei said he wanted to get to know Silvye, but aside from the Hot Spring trip he barely did try to get to know her, unless he needed help.
Overall the series left me very dissapointed with its plot, though it did left me with several good characters (though we will never see them again) in Silvye and Seika.
