I saw Shirely just week before she turn lisa for MyAsianGFE. Nothing is weird or off with her, she was glad to see me and remember me only 2 or 3 session i've seen her before. She said i was her favorite client of all time (i'm sure she said to almost every of her clients) but nothing is off. Girls comes and goes between agency. Given AS/PP ran by chinese MMS and if Natasha is Chinese, so it's not a surprise if she decide to change the enviornment a bit.
Or some of her client decide to convince her to join another agency, who knows.....
