Many people in the TV series "Ode to Joy" envy Wumei's friendship. They have transcended classes, experienced many things, and become the most important people in each other's lives. In my opinion, the friendship between Andy and Qu Xiaoxiao is from the same class and mutual relationship. Qu Xiaoxiao had a good relationship with Andy and even invited Andy to his home. Andy also helped Qu Xiaoxiao's mother transfer property. That's because these things are just a matter of effort for Andy.
Andy in the original book is not averse to making friends, she likes the smell of fireworks. Qu Xiaoxiao needs Andy's professionalism and the connections behind Andy. This is a friendship she deliberately maintains.
Andy has a clear distinction between love and hate. Once she finds that this relationship is meaningless to her or that it is not good for her, she will give up this friendship.
