Heaven help me, the relationship between these two is already breaking my heart and promising worse damage in the future!
They’re worrying about each other and clearly fighting hard not to let the other person know how much they’re suffering. So basically dragged himself from his nearly death bed to find her because she was alone and Soo, despite being tortured to the point of fainting, is both glad to see him and yet worried about him not resting enough to recover well.
Side note: I love how the first thing Soo asked when she spoke with Wook was So’s wellbeing. As much as it irked Wook, it thrilled me. Wook’s mask of gentility is waning and it’s fascinating to watch. Every part of this drama is exciting and makes me crave the next episode.
