It had. I’m not saying Key has never worked with inner conflicts before, just that not all the character plots and development were built around this, Charlotte is probably going to be the first.
CLANNAD spoiler: Fuko, for example, had to deal with an external problem, her comatose.
Kanon spoiler: Makoto’s plot was about her wanting to see Yuichi again, and turning into a human, but had a shorter lifetime.
AIR spoiler: Misuzu had to deal with a curse.
Little Busters! spoiler: Komari was mentally affected by the death of her brother.
Those are some examples about how there’s always other kind of conflict, that isn’t internal in Key’s works. I dunno about Planetarian, but AB! had Yui’s past, that I don’t think it was an internal thing. This is why I’m saying Charlotte can be the first to explore all the characters’ conflicts inside themselves.
