Woah, I wasn’t expecting a leading lady casting this quickly and also did not expect this particular one. Yoona will be joining Lee Jong Seok in the upcoming legal drama Big Mouth, which will be the first time they are working together and probably about time. Both are top of the small list of drama leads in their age group and this pairing will definitely generate buzz. Lee Jong Seok plays the titular Big Mouth, a lawyer with just a 10% success rate who only knows how to run his mouth, but suddenly finds his life and legal practice thrust into a mysterious conspiracy when he takes on a murder case. Yoona will be playing his wife who isn’t just a flower vase but a former capable model with class who gradually turns into a brazen woman with plenty of curse words. The drama is from the PD of While You Were Sleeping and Start-up, with the script by the screenwriter of Empress Ki. The drama is slated for end of 2021 on tvN.
