I agree on the IC Illustrations. Much more to the point.
Let's take another swing at concerns.
OS - Obtaining
I was having trouble with this because watching the movie again Approach / Attitude, Self-Interest / Morality seemed so strong, but I couldn't think of a good illustration. I decided to look up some gists on Subtext and saw things like "Finishing what you started", "Returning home", and "Escaping a monster", and it clicked for me.
MC - Subconscious
Closure and Denial stick out the most here. He tells Su-an in the car you always have to finish what you start. Not finishing is worse than not doing it at all (He gets cut off there, but I think that's where he's going with it). Denial is the strongest. He simply will not ever admit he made a mistake. He refuses to apologize to Sang-hwa, he tells his assistant that they did nothing wrong event though it's implied that they were very deeply invested in the company that made the virus/chemical, and pulling all their money out after reports of the leak was a bad idea.
IC - Future
Sang-hwa putting off choosing a baby name. Sacrificing himself to buy them time to escape. He chooses a name right before he dies. He chooses Seok-woo to protect his wife. Sang-hwa and Su-an's preconceptions about Seok-woo. ("He's a bloodsucker" "You're the reason mom left" "You don't care about anyone but yourself") One day she'll realize everything you did was for her. Maybe you're not such a bad guy after all.
RS - Becoming
Becoming a functioning father/daughter relationship. Becoming a couple. Becoming parents. Benchmark would be being. The more we're they're for each other the closer we become.
Am I in the ballpark? Haha
