Season 2 eps 1 - screen shot analysis

This proves that Ms Huang is Ms Casey--?

In the last screen shot, where we see a grey image of Ms Casey. There is a number on the bottom right (NP400253). I googled that and it took me to a pdf of donations to a Chinese company

(https://wanhai-charity.org.tw/wp-content/uploads/2022/06/2013%E4%B8%8D%E9%9B%A2%E4%B8%8D%E6%A3%84%E6%8D%90%E6%AC%BE%E8%8A%B3%E5%90%8D%E9%8C%84.pdf)

If you scroll down the list of names and find that number--- Google translate says the name is "Huang Jiazhen".

Also the top line of the document states "Wan Hai Lines Social Welfare Charity Foundation Never Give Up, Let Love Continue" maybe a nod to Mark's love?
