Love is presented in many ways throughout Alien Stage: For Mizi and Sua, it's codependent, romantic to a worrying extent. For Ivan and Till, it's one sided, unrequited, and painful.
And for Hyuna and Luka, it's a curse.
Not only a curse, but one that haunts them. Jacob once told Hyuna to "Forgive yourself", which, to her, was misplaced. She could have forgiven herself. It was Luka who she couldn't forgive. But, in the end, she couldn't fulfill the legacy. She couldn't forgive herself for loving Luka. She couldn't forgive Luka for killing who she loved. And so, what did she do? She passed on the legacy.
The words "Forgive yourself" didn't help her. They built who she was, but in the worst possible way. She couldn't take his words, because she didn't consider herself the culprit, but the one she resented.
She told this curse, "Forgive yourself" again. She told them to Luka, sentence that almost sounded mocking on her lips. She couldn't have died before because she had to keep moving forward, but now, the pressure wasn't on her shoulders anymore.
She loves Luka, of course she does. But she cannot possibly forgive him. She knows he doesn't realize the suffering he inflicts. It's ironic, he's so unbearably smart, solving puzzles in a matter of seconds, but he doesn't know how to take in the real world, and the feelings of the ones around him, the most important 'puzzle' of them all. So, she gives him the biggest dilemma of his life. It's harsh, cruel, messed up in every sense. It's the puzzle she knew he could never solve, because she herself, who knew humanity, couldn't. Hyuna knew Luka loved her more than himself. And Hyuna cared for Hyunwoo more than for herself. Luka killed Hyunwoo, and so, Hyuna repaid him with the same coin, an eye for an eye. With an act that is the ultimate sacrifice, and the ultimate revenge.
As I have said, Hyuna knew the love he had for her, beyond the limits of his own body. She must've known how much her act would destroy his world: a fate worse than death. Her kind tone, telling him to take as much time as he needs to solve the newfound question she has proposed in such an ugly way, appears almost taunting.
And the way she holds him in her arms, purposefully close, and looks into his eyes, makes it just so much more painful. And yet, when she speaks her soul, passes everything she was carrying on her shoulders, over to him, her face is hidden away, buried in his shoulder. She's free. She finally had her revenge. She can forgive him, and then herself, even though the price was destroying him, without building him up again. Leaving him like pieces of a puzzle that never got solved. She's been cruelly betrayed, and she, even more cruelly, fed him his own medicine.
Hyuna is haunted by both Hyunwoo and Luka, similar to how Mizi is haunted by Sua. Hyunwoo brings the horror aspect: the bloodied blouse and head, while Luka has the smile that Sua has in the imaginations. The two people she loved most: the one who couldn't forgive her because she didn't get to apologize, and the one she didn't forgive. It's all so incredibly complex: she hates and loves, she resents and adores. Hyuna can't pick anymore. We're shown that she's such an active person, sociable, loving, having a whole group of humans just like her, and yet, we're told that she thinks all of them are selfish, even if they seem altruistic. She doesn't trust them, it seems it's a facade. In this, Luka and Hyuna are similar, but divided by the fact he wants to conceal his emotions, and she wants to make them more visible.
This page, specifically, made me click MiziSua and HyuLuka together. They look scarily alike. The same lovey-dovey expression, versus the distressed one of the lover, even the slight glow that Luka has is similar. I think this is meant to show that they still depend on each other, despite the fact that Hyuna seems to resent him so much.
Hyuna says Luka doesn't know the meaning of love. That the only thing he's ever shown, the only thing he genuinely knows, is suffering, and that his abilities basically stop at inflicting the same. (At least, emotional ones.) This is a parallel to Ivan, in my opinion, who didn't know love either, but he liked the idea of it. Instead, Luka loved with everything he had, even though he had no idea what it truly was. His love is obsessive, and somehow, so impossibly innocent at the same time. Because in a way, he's still a child. When he sees Hyuna, he becomes immature again, his facade of control dissipating into thin air. He mocked Mizi for her inability, but he's even worse.
According to his ear monitor, his heart was beating out of his chest. He could hear his own erratic heartbeat. It's painful, how happy he was, how excited, to be in her arms again. And yet, despite the love, the embrace was just as much of revenge.
Ever since Wiege, we've seen Luka smile so much. Just for him to never truly smile again.
I am a fan of the gentleness that Hyuna treats young Luka with. She seems awfully attached to the image of that innocence she knew. But it's not like Mizi's idea of Sua, the perfect one. It's an image she can't bear seeing again. "I couldn't stand seeing myself on those posters, because I knew exactly the face the you'd have. Yes, I bet you were smiling ear to ear." We've only seen him like this for the first time, but to her, it was so familiar, even years apart, she still knew.
Another thing I have noticed is that Hyunwoo's grave is right infront of a tree, almost separated from the others, just the way Luka was sitting before Hyuna found him. Now, this time, Hyunwoo lost Hyuna, and he's forever forced to be lonely in the garden he'll never grow out of.
Hyuna wanted to give Luka a rubik's cube he wouldn't be able to solve, something difficult. A rubik's cube can represent human nature, who Luka seems to have mastered completely. But Hyuna finally manages to postpone him: the puzzle is herself.
And in the end, after Hyuna's body goes limp, he finally manages to take her in his arms. He promised that there, she'd be safe, but he didn't manage to keep her that way. And suddenly, the words "My Savior" from Ruler of my Heart are awfully true.
