I'll fix it if this goes through, but I'm seeing info that isn't actually information, but an opinion of an individual.
Yumeko's "dream, love blah-blah" being related to Love Plus and Dream Club is borderline opinion (because what she's saying actually reflects the outcome of Ryo's scenario pretty well), but "Her character role and personality was changed at the last minute when the game's sales completely crashed after the release of Pokemon Heart Gold & Soul Silver " has zero source and sound like an opinion.
Plus, would the programmers change her personality at the last minute, when there's 5 days to release and the game's gone gold already? I mean, really? How can they change the game when it's already shipped to stores?
