JTBC's upcoming drama '18 again' has released a rib-tickling new teaser!

Inspired by the American film '17 again,' JBTC's '18 again' tells about the story of a husband fighting for her marriage from divorce who suddenly turned back to his prime age 18 years ago. The new series will be the first drama project of director Ha Byung Hoon since helming KBS 2TV's 'Go Back Couple.'

Playing the 37-year-old Hong Dae Young is Yoon Sang Hyun, while the younger version of the character Hong Dae Young will be taken by Lee Do Hyun, who mysteriously transformed back to his 18-year-old body. Instead of using his real name, he will go by the name Go Woo-Young to hide his identity.

The sneak peek video started with a teacher informing the class of a new classmate named Go Woo Young. Go Woo was shown in his 37-year old self instead, as he was preparing to introduce himself in front of the whole class. He introduced himself, saying, "Hello, I'm Hong Dae, I mean, Go Woo Young. I am 18 years old." He continued asking his classmates to take good care of him and make a large heart above his head.

Hong Dae Young chose to sit beside Hong Shi Ah (Noh Jung Ui), his daughter. Giving a smile to his daughter, who is his new seatmate, Hong Si Ah annoyingly expressed, "Why are you smiling?" The disappointed Hong Dae Young turned around and showed a friendly face to Hong Shi Woo (Ryeo Woon), his son, and the twin brother of Hong Shi Ah. Like his sister, he responded, "Why are you looking at me. Lower your gaze."

Transforming back to Go Woo, Hong Dae Young expressed through a voice-over, "The story of a father joining his children in the same class after returning to his golden age from 18 years ago."

'18 Again' will give you tons of smiles and laughter starting September 7 at 9:30 PM, KST. Check out the new trailer below.
