@Tamerlane It's even worse if she ends up doing something one personality wants to do, but ends up switching halfway through to reveal that the other personality didn't actually want to do it. I guess this is why both personalities need to really be honest about that stuff, especially with each other.
But the previous chapter makes me wonder if their wishes are necessarily opposite to each other. Haruka claims that she came to be because of Akiha's hesitance over certain things, so it may be possible that Akiha shares Haruka's desire, but is more prone to thinking about the risks of their decisions.
