Explanation about how to make pie.

"Vion I've always been wondering. Why is Hana so... Hana?" Tom has been curious about Hana's behavior for a long time.
"Well Hana acts like this because she feels safe. Just like how Vinna is so cheery most the time. Hana pretends she's a bizarre princess I think in a world where everyone is nice and friendly to her which in here she feels like that. Vinna act cheerful and tough but she's actually quite meek on her own. If Hana wasn't with her I don't think Vinna will be as cheerful as she is." Vion explains about her sisters.
"So Hana is acting weird for the sake of Vinna or is Vinna acting cheerful so Hana can be Hana?"
"Even I am not too sure which way it is but I think Hana is Vinna's spirit support more. Although it's deceiving Hana is a lot more strong willed than she acts."
"I see."
