Judgement, the sun, the hierophant
Judgement: Would your muse ever go back to their most recent ex-lover?
It’s a matter of what the circumstances of the breakup were, if they were amicable, if she believes they were just going through a rough patch, if she believes there’s a chance things could actually work out if they BOTH just tried a little bit harder, then yes she would go back to an old relationship.
The Sun: What was the happiest moment of your muse's life?
There’s a myriad of moments to choose from, when she first discovered her craft, the first time she was able to perform on stage without any fears or doubts, when she first met Naoto of course, but the answer has to go to when Naoto proposed to her. It was the moment that she knew for the first time that all was right with the world, that her love, would be hers forever, that truly and completely they would be together forever, that she would never be lonely, or experience the horrors of that day, ever again, that she could rest easy in the knowledge that her life would be one worth telling stories about.
The Hierophant: What is one rule or law your muse would never break?
Being married to pseudo-cop the answer is all of them, but being realistic, probably theft. An attempted theft-turned murder was what started this whole spiral of misery in the first place. Even though it would never get to that point to begin with, Mio just doesn’t have it in her to steal from others, take what is rightfully theirs, however much her heart might desire the object in question.
