My gosh, Botun Greep Sood Tai (“The last peony petal”) is airing real soon. It has not been confirmed yet but people have beens saying it will take up the next Monday-Tuesday time slot for Ch3. Possibly airing on September 16. If not September 16, it will definitely air within the month of September.
The story will center around 3 Chinese-Thai sisters played by Aff Taksaorn, Ploy Cherman, and Oh Petlada whose father runs a opera house in 1950s or maybe 1960s Thailand.
Eldest sister is played by Oh Petlada and is paired with Tah Warit.
Ploy Cherman plays the charming middle sister and is paired with Tui Kriatamol.
Feisty youngest sister is played by Aff Taksaorn and is paired with Aum Atichart, Ateam!
