SEE ALSO: Taecyeon plans to show a new side of himself on 'Very Good Days'

As the drama takes place in Gyeongbuk, Gyeongju, the actors will be using the satoori associated with the region. Taecyeon, who previously used dialect on 'Cinderella Sister', brushed up on his accent by conversing with old friends in his hometown of Busan for a few days. Park Joo Hyung, who is from Seoul and does not use the dialect, also stayed in a guest house in Busan to learn how to speak with the accent and slang of the region from the natives.

A JYP Entertainment rep told Star News on the 29th, "In the case of Taecyeon, because he is from Busan and uses satoori, there are no difficulties... Taecyeon is learning from observing the acting and the small details of Ryu Seung Soo, whom he stars with as brothers."

'Very Good Days' will take viewers on the life journey of a man who grows up poor but ends up becoming a successful prosecutor and returns to his hometown 15 years later.

The drama will premiere following the conclusion of 'The Wang Family' on February 22 at 7:55 PM KST!
