I have tried it with the guide today but she just tells Ryo the usual stuff and that there's nothing new she can read afterwards.
There definately have to be other factors that make you get this.
Since I was sure that this dialogue really existet I searched through the files and actually found the lines! I made a little conversation out of the files. I'm not sure if they come directly in this order (especially Ryo's reactions) but I'm sure they are related and it makes sense. Ryo's a real ass here once more...
Here you go:
http://spindash.de/forum/master_dl/ryofortune.mp3There are actually many neat things among the palm readings of this girl. They go through the whole story until the end of disc 3. While she is traveling to Hong Kong with Ryo it's impossible to get readings from her after Ryo reached the COGH since the whole area is shut down for remodeling. She might move to somewhere else at that point but I haven't found her.
Anyway... she's really jealous about other girls that Ryo will meet. She makes negative readings about Joy, Xiuying and Fangmei and uses key infos like blue dresses and red hair. Afterwards she allways says something about herself, like that her blue dress doesn't mean anything bad and that she is happy not to have red hair and such. She's a real fun girl actually. Didn't knew they put so much extra stuff into the palm reading.
