Their youthful beauty and outstanding acting have made audiences overlook the performers' age difference.
Two of the many key things that help actors depict their roles well are the use of appropriate visuals and the ability to role-play.
This factor also makes the audience forget the actors' true ages. In terms of their roles, the characters in the following Korean shows on screen appear to be highly similar.
However, many viewers are taken aback by the fact that they are so far off in age in real life.
Jung Hae In, Kim Min Kyu
Comrade Lim Soo Ho (Jung Hae In) and Comrade Joo Gyeok Chan (Kim Min Kyu) are around the same age in "Snowdrop".
Standing next to each other, these two characters appear to be two similar-aged, like-minded comrades.
However, Jung Hae In is 6 years older than Kim Min Kyu in real life, and the two have a very close brotherly bond.
Hwang In Yeop, Cha Eun Woo
Han Seo Joon (Hwang In Yeop) and Lee Su Ho (Cha Eun Woo) are longstanding best friends in "True Beauty", and they are both of the same age and in the same class.
With Hwang In Yeop's youthful appearance and Cha Eun Woo's maturity, it's tough to believe the two actors are only 6 years apart in age.
Park Min Young, Seo Kang Joon
It's incredibly easy to match Park Min Young's age-hacked appearance with Seo Kang Joon, a 7-year-old youngster.
These two sisters play the roles Mok Hae Won and Lim Eun Seob, who are close friends before becoming lovers.
Their camaraderie and flawless visuals served to bridge the generation gap and engage viewers in "When the Weather Is Fine."
Lee Joo Myung, Choi Hyun Wook
Ji Seung Wan (Lee Joo Myung) and Moon Ji Woong (Choi Hyun Wook) of "Twenty Five, Twenty One" are the most renowned same-age couple recently.
Actors Lee Hyun Wook and Lee Joo Myung are both 20 years old.
Both of their performances are so smooth and at ease that the 8-year age difference is forgotten.
Lee Yoo Mi, Park Ji Ho
Lee Na Yeon (Lee Yoo Mi) and Nam On Jo (Park Ji Ho), classmates, have undoubtedly made a lasting effect on fans of the series "All Of Us Are Dead."
Many people were startled to learn that actress Park Ji Ho was only 18 years old, 11 years younger than "classmate" Lee Yoo Mi.
Their acting and visuals were so outstanding that many people were surprised to learn that she was just 18 years old.
