6 K-Dramas With Big Age Gaps Between The Romantic Leads

It happens more often than we realize.

Recently, actor Go Soo was announced to star in a K-Drama with OH MY GIRL‘s Arin, and the news drew quite some frowns as people realized the two actors have an age gap of 21 years! Though neither the plot nor the genre of the show is known to the public yet, people showed concern assuming that these two actors might play love interests of each other.

Even the recent Netflix global hit, The Glory, also received negative attention from quite a lot of netizens who were sour about the 14-year age difference between the leads, Song Hye Kyo and Lee Do Hyun. Similarly, Eve‘s lead casting was also criticized for the 12-year age gap between Seo Ye Ji and Park Byung Eun.

2. Marriage Contract

There is hardly a K-Drama fan who doesn’t know about this iconic K-Drama. The story is about Kim Shin (Gong Yoo), an immortal goblin who is on a search to find a human bride who can remove an invisible sword from his chest and end his life. His search ends when a school student Ji Eun Tak (Kim Go Eun), confesses to him that she is the chosen one. This is probably the only drama where the on-screen age difference between the leads was much more in the talks than the off-screen one. Gong Yoo and Kim Go Eun share an age gap of 12 years, the former being 43 and the latter being 31 this year. But in the show, Kim Shin and Ji Eun Tak had an age difference of 920 years!
