"Sia is deeply sensitive, with artistic talent and keen intuition. She even conducts MBTI analyses for her four cats, observing each one in great detail," Xie says. "She also paints — she created the animated cover art for this episode."

Xie recalled that the first time she saw Sia and Tyrion in September 2023 left a profound impact. "Surrounded by towering buildings, they held hands and seemed small, but ready to face any challenge together," Xie says.

That evening in Kunming, Yunnan province, Sia and Tyrion, wearing colorful masks Sia painted, performed a song she had written:

"Sometimes I wonder what could become of us,

If we'd never crushed our worlds.

Now when they see us,

They see disasters.

But in my eyes, we looked like

Fireworks."
