@seedht1 There are many other ways to show their relationship falling apart. For example both of them working too much and have no time to talk to each other etc.
@seedht1 Going back to the initial point that L cooked a lot of fried food to annoy K because he had too much overtime. I think the key problem here for me is that she is literally his boss. She should have been supporting him at work to reduce his workload. But she didn’t.
@seedht1 Also director said he wants to express the „distance“ between L and K in the first half of the movie. They are not happy about their life in Plant and their relationship fell apart.
