I kinda see what you mean, but I believe it is intentional since it really fits with the theme and characters who are living in an unforgiving world and tackling daily hardships together, especially as a gay couple, which is pretty tabu in korea. I think it’s beautiful how that constant anxiety is portrayed in their eyes and I think a lot of people can relate to the feeling of constantly feeling uncomfortable in the world, despite there being some good moments. The feeling of uncertainty also goes in line with the new and curious love they have for each other, They must be pretty nervous, and every boundary they cross will feel like a whole new world. :3
I don’t know why, but the eyes are always popping no matter what emotions. I don’t know if it’s intentional or not, it just makes even the good moments look like something horrid is gonna happen. And it never does, gives me anxiety for no reason. If it’s unintentional, I suggest improving the eyes along with emotions, thank you.
