"Zomst is better than Alnst"
respect where you learned about these characters and their conflicts because without canon, you wouldn't understand half of it
Mizi and Sua never shared the stage before they became zombies. Constantly facing failure, Mizi did whatever it took to hold onto her chance. Suah always wanted to be close to her, but Mizi was already completely drained and broken.
That Mizi's face is almost completely obscured during the zombie stage seems to symbolize how, as implied in Mizisua's flashback, Mizi gradually came to be consumed by the public solely for her sensual image despite being an idol. That makes the scene feel even more symbolic.
