Seems like they are currently filming at least 2 of the stories - Jai Pisut & Duj Apsorn. Not sure about the rest though.
Edited: Just noticed an article saying the cast went to Switzerland to shoot Pon Chiwan too.
Wait a minute. I just remembered her previous post on Girl in the Sunny Place and googled it. She said "Watarai Mao", the name of the main character in that novel/film. LOL
She seems to like that story a lot :)
And thanks a lot for your reply! ♥
