Gege Akutami owes me therapy

Some symbolism from the last alien stage episode!

It's kind of obvious that the heart symbolise their feelings of love, Mizi and Sua completing each other, but it's also what makes them unable to truly communicate with one another, Ivan forcing Till to take his, Hyuna refuse to gives the heart to Luka and ends up breaking it while Luka was already more than ready to give his.

But the the black liquid would also represent the toxicity that is always shown to come with love in this show, it goes in Mizi and Sua's eyes because their feelings for each other blinds them on their deeper nature, it explodes on Till as Ivan tries to force him to take the heart but he ends up only receiving the poison, and for Hyuna it breaks on her body after she hid it and spills like blood on her.
