In this unique melo-romance that tackles mental health, author and DJ Jang Jae Yeol (In Sung) meets his match in psychiatrist Ji Hae Soo (Hyo Jin).

We thought we’d put at least one installment of tvN’s Reply series on this list because being a part of all three dramas is a highlight of Dong Il’s career. He plays a different father in each drama, but his character always uses his real name. Reply 1988 tells the story of five friends living in 1988 and the challenges they face growing up—including love and family problems. Dong Il plays cheerful Duk Seon’s (Hye Ri) dad, who racks up some debts after his friend borrows money from him and disappears. He loves his family a lot and does his best to make ends meet.

Dong Il’s impressive portfolio features plenty of popular dramas. This includes hit fantasy rom-com Legend Of The Blue Sea, which stars Hallyu sensations Jun Ji Hyun and Lee Min Ho. The drama revolves around the innocent mermaid Shim Cheong (Ji Hyun) who falls for human con artist Heo Joon Jae (Min Ho). As Shim Cheong tries to adjust to daily life as a human, we also get flashbacks of her past life in the Joseon era. Dong Il plays Ma Dae Young, a fugitive Joon Jae’s stepmother hires to kill him. Dae Young makes several attempts on both Joon Jae’s and Shim Cheong’s lives. Dong Il won a Special Award for acting at the 24th SBS Drama Awards for this role.

4. Miss Hammurabi (2018)

Who else is in it: Go Ara, Kim Myung Soo, Ryu Deok Hwan, Lee Elijah

This critically acclaimed legal drama gives audiences a glimpse into the lives of South Korea’s judges. The story is based on a novel written by Moon Yoo Seok, chief judge of the Seoul Eastern District Court. Unlike other dramas in the same genre, it focuses on the intricacies and struggles judges face when making decisions, painting a more humanized picture of them. The main storyline centers on Park Cha Oh Reum (Ara), a newbie judge who can’t stand injustice. She butts heads with Lim Ba Reun (Myung Soo), a logical judge who only looks at the cold hard facts. Dong Il brilliantly plays Chief Judge Han Se Sang, a righteous man who guides them with a firm hand.


5. Trap (2019)

Who else is in it: Lee Seo Jin, Lim Hwa Young, Seo Young Hee

If you’re in the mood for something *mind-blowing*, OCN thriller Trap is sure to take you for a ride. In it, Kang Woo Hyun (Seo Jin), a celebrity announcer with political aspirations, experiences hell on earth when he takes his wife and son up to the mountains for a vacation and encounters a huntsman. He returns to the city alive, but what happened to his family and who is responsible? Dong Il plays Go Dong Kook, an experienced detective who takes on Woo Hyun’s case. As the story unfolds, horrifying facts come to light and Dong Kook realizes the stakes are even higher than he anticipated.

This time around, Dong Il stars in a horror thriller. If you’re scared of ghosts and the grotesque, this might not be your cup of tea. If you love Asian horror movies, though, this one’s for you.

We love how Dong Il keeps evolving by picking so many different drama genres. Sisyphus: The Myth is a sci-fi thriller that takes audiences to a world where time travel is possible. Tae Sul (Seung Woo), genius CEO of the company Quantum and Time, gets a glimpse of his supposedly dead brother, Tae San (Joon Seok), while trying to stop the airplane he’s riding from crashing. As he searches for his brother, he meets Seo Hae (Shin Hye), a woman from the future, who wants to save the world from destruction.

Ji Hyun plays Yi Kang, the best ranger of the group, nicknamed “Mountain Ghost God” for her uncanny navigation skills. Despite this, she actually hates the mountains. Ji Hoon is Hyun Jo, a military captain who becomes a ranger after getting visions of death on the mountains.
