he doesn't know why but he felt like Anna doesn't hate him as much as before, even though she does hate him but not like before after seeing her not doing any of those reactions showing disgust she is towards him.
Allen leans to Anna's ear and whispers "I am so cold", she didn't tell anything, he smiles and hugs her tighter than before as a smile forms on his lips, and they stood there for like 10 mins, Anna broke the hug and just started to walk inside without talking anything, Allen walks back of her like a little puppy asking with his sweet voice "Anna, are you still angry at me?".
