Du Yue took two quick steps forward and reached out to open the door. The metal doorknob was so cold that she could feel the bone-piercing chill through her gloves. She used all her strength to open the door and saw that He Xing had also wrapped himself up like a bear. Other than his eyes, everything else was covered.
Du Yue looked him in the eye and could clearly see that the worry in He Xing's eyes had disappeared. He seemed to be smiling. She could hear his muffled voice from the mask, and his tone was excited. "It's great that you're not sleeping. I was worried that the temperature would drop too suddenly and something might happen to you."
Du Yue's eyes curved into crescents. The two of them had a tacit understanding. "Have you lit the furnace at home?" Du Yue asked him.
"Yes, yes, I've lit it." He Xing nodded. "Do you still need anything at home? If you need something, tell me. I'll bring it to you later."
