So in the end it was all about drug addiction, only the drug was power.
What a perfect ending. Sangwoo's last scene, basically a rich junkie tripping alone in a big room, was full of pathos. By winning, he lost in the end.
The final scene with Suhyeon and Yeonghoo was moving. I can understand her tears. Suhyeon denied her the last consolation she had, the right to wreck herself in tobacco and alcohol. She knows that from now on, she'll be controlled like a child or a puppet, and that all her dreams of an independent adult life have been shattered. And it doesn't help that Suhyeon seems to be taking relish from being in control.
This is a fantastic, textbook example of a downer ending. Sangwoo totally embraced villainy and the scene of his smirking while Yuna was harassed and removed by Jisang thugs was sickening and sad to see. The two echoes in the chapter, of his conversation with Mijeong about climbing up endlessly, and of the narrator's words in the first chapter, were revealed hollow. In the end, Sangwoo couldn't even bring himself to let Suhyeon have the palliative, probably because he fears Suhyeon will leave for good if he gets it, and thus he's keeping the only person who took his side in a leash after shattering his personality.
On a side note, I can't help feeling that Sangwoo's self-deception about how good it is to live your life climbing up is among the best explanations to the billionaire mindset I've seen in pop culture.
Bravo, Kang Hyung-gyu. Looking forward to your afterword… and to your next.
