Achu is a good girl, and she keeps going strong all the way. She knows when injustice will be repaid, and she also knows that the deceased is dead. But she still carried the big knife into the wind and walked down in the rain. She just wanted an explanation, regardless of whether the ending was happy or not.
Amo is a good young man and accompanies Li Xin all the way. He didn't know how long he could walk with her, he just stood beside A Chu silently. Being able to cook a bowl of noodles for her late at night and holding her to sleep on a cold night was all his happiness.
