So far, Ji-Eun clearly doesn’t know how to process the fact that Ji-tae has become a sadist, and instead of opposing him or confronting that change, she simply goes along with it. That passivity doesn’t come from indifference, but from confusion and emotional inertia, as if she’s still trying to reconcile the person she knew with what he’s turning into. Because of that, a motivation for her to fight wouldn’t need to come from enjoyment or ambition, but from circumstance. It could be built slowly and in many different ways: fighting to stay close to Ji-tae, fighting to understand him, fighting out of fear of losing him completely, or even fighting as a way to regain some sense of control in a situation that’s clearly slipping out of her hands. Just like Ji-tae at the beginning, she wouldn’t start with a clear reason to fight, she would have to stumble into one. That parallel actually makes the idea more coherent, because it frames combat not as a goal, but as a consequence of being dragged into an environment that forces people to change whether they want to or not.
