According to a short video posted by one of the casts in the same work, Sung's role seems to be a gangster who facilitates human trafficking.
I started reading more about human trafficking and getting really depressed. It's so sad to know what's going on in real world in real time. Plus, a long and sad history in each country. We all know it exists somewhere not too far from where we live. I was a bit surprised to learn that Japan is categorized in Tier 2 in Ranking System while some other neighbor countries like South Korean and Taiwan are in Tier 1. That's a shocking fact to me.
Anyway, hope this movie show us something we can feel hopeful about the future. We don't want to enjoy our convenience at a cost of someone else's hardship.
By the way, it seems like Sung himself has been inactive in Twitter/Instagram/Facebook lately. I need to remind him that we want his selfie. Though we can see him through someone else's posting, we feel more connected if Sung posts something on his own. Please don't hesitate to do selfie and share. We want to hear from you.
