Why does Andy like Xiaobao? What is the biggest difference between him and Wei Wei?

The plot of the TV series is not logical, and Brother Wei is described as a thoughtful and mature man. However, Andy was not informed about the marriage recognition in advance and Wei Guoqiang was rashly introduced into Andy's life. This was a flaw on the screenwriter's part and contradicted the overall character design. It is also far-fetched that Andy was angry with Brother Wei because of Wei Guoqiang, which led to the end of the love affair. If there is any difference between Bao Yifan and Wei Wei, it is their cheerful personality, which complements Andy.
