In "Village" is Jang Hee Jin really the older sister of Moon Geun Young.
"Village, Achiara's secret" is about a quiet village that gets turned upside down with a murder case. Though it was a town with barely any crimes, everyone turns against each other in hopes to find the true murderer.
On the 5th episode of SBS Wednesday/Thursday drama "Village: Achiara's Secret'" broadcast on October 21st, Han So Eun (played by Moon Geun Young) started chasing after the whereabouts of her sister.
On this day, Han So Yoon went to see Han So Yoon's aunt, Suh Ki Hyun (played by On Joo Wan). The aunt talked about the sister and said, "She kept on asking about where she was from. So I said Achiara, that she was from Achiara in Kangwon province."
At this, Han So Yoon started to talk about the process in which she came to Korea. Han So Yoon said, "This must be the person that sent the letter, my sister. There's a seal from Achiara. My sister must've been looking for our birth mother in Achiara."
With that, by coincidence, she found out how her sister came to Achiara.
Nonetheless, Suh Ki Hyun said, "I also thought that Han So Jung had come from Achiara but don't you think that's too hard? I wouldn't have created a riddle like this."
