winter evening. you and your boyfriend Yinxing decided to take a walk. the sky was already dark, there was a thin layer of snow, dim light was burning in the windows and silhouettes of people could be seen. you raised your head up, looking at the sky, as you felt something warm touching your hand, it was Yinxing's hand. the man was smiling, the cold on his cheeks formed a warm blush. he offers to take his hand.
