According to Soompi's article from March, she's confirmed.https://www.soompi.com/article/1390298wpp/girls-generations-yoona-confirms-for-upcoming-jtbc-drama-with-hwang-jung-min
Ep 4 is postponed. Newplus Original said: "The production of episodes 4~6 is now in extension due to overseas locations constraints. We appreciate your continuous support and patience!"
What started from exam cheating in the classroom escalated to stealing a national test paper. These are not your everyday students. They’re a reflection of the cheating that happens at every level in Thai society.
Lin: (Plearnpichaya Komalarajun) A genius who cheats for revenge against the school. Hoping to reclaim the tea money her father (Saksit Tangthong) paid to the Headmistress (Apasiri Chantrasmi).
Bank: (Jinjett Wattanasin) A son who is dutiful to his mother (Ratchanok Sangchuto) but has to cheat because fate is always playing tricks with him.
Pat: (Paris Intarakomalyasut) The son of a wealthy family who cheats because he’s pressured by his father (Willie McIntosh) who is the family’s dictator.
Grace: (Sawanya Paisarnpayak) It's not clear why this young girl cheats. Is it because she’s swayed by her friends? For the love of her life? Or is it really for herself?
Guaranteed with different versions and various forms of drama unlike the movie. Whether it be family drama between Lin and her mother (Rasee Diskul Na Ayudhya), who left her to start a new family. Love/Revenge drama between Lin – Bank and Pat – Grace. Drama exposing the dark side of exam “stand-ins”, with Ms Music (Siraphan Wattanachinda) the sly head-hunter tutor.
Don’t miss the conclusion that is unlike the movie version, because their cheating is not only bold but also challenging at a national level.
I only like trio fl, second couple, and third couple but sadly not really many parts :(
Also, there are some plot holes
