### Summary
As Ruby auditions for the role of her mother, Ai, she struggles to connect with the part, leading the director to praise her hard work but doubt her ability to carry a lead role. The true breakthrough comes not from direction but from a piercing observation by Kana Arima. The genius actress asserts that Ruby cannot possibly understand Ai because she doesn't even understand herself—is she Sarina, the girl abandoned by her mother, or Ruby, the cherished daughter of an idol? This forces Ruby into a deep identity crisis, where her quest to portray a legend becomes an agonizing search for her own fractured self.
