Netflix's Squid Game is fast becoming the streaming giant's most popular show ever.
And now, fans of the show have revealed a heartbreaking detail non-Korean speakers may have missed.
One of the show's central characters Kang Sae-byeo, played by Jung Ho-yeon, partakes in the game to help get her brother out of an orphanage and rescue her mother captured in China.
But several Korean-speaking viewers have pointed out that the character is actually
from North Korean and tries to hide her accent around the other players.
Fans flocked to social media to point out on important detail,
with one writing: 'In the scene where Sae-byeok talks to her younger brother,
she initially talks in the standard Seoul dialect,
but immediately switches to the North Korean accent when her brother starts becoming distressed.'
While one non-Korean viewer commented: 'Don't know Korean,
but I definitely noticed the change, this is cool to know though.'
'One thing I found kind of interesting was how Sae Byeok was treated by some of the other players
for being North Korean,' a third fan added.
Squid Game has soared to popularity globally ever since
its release last month - with Netflix co-CEO Ted Sarandos saying it has a 'very good chance'
of becoming the streamer's most popular show yet.
The South Korean series is a survival thriller set in modern-day Seoul,
where a group of 456 people are
invited to play a series of children's games with the chance to win a huge amount of money -
but if you lose in the game, you lose your life.
On Tuesday, News.com.au claimed many viewers are watching the hugely popular series the 'wrong' way
as they are watching either the English-language dub or reading the closed caption subtitles.
The closed caption subtitles simply sub the English dub of the series, instead of conveying
the official Korean to English subtitles.
For non-Korean speakers, the official subtitled version is recommended for the best experience.
Kiwi director Taika Waititi has even weighed into the debate, urging Netflix users to avoid the English dub.
'You don't have to watch Squid Game dubbed in English,' he tweeted to his million followers this week.
