Dotori

The female protagonist, Lee Ja Eun, has always been at the forefront of the North Korean government's propaganda policy by working as a singer in the city's propaganda corps, but due to lack of food supply, she survives with her friends in the mountains by giving them acorns. Additionally, her boyfriend was imprisoned for watching a South Korean video and was on the verge of execution, and a close acquaintance of hers. Her friends were caught while trying to escape from North Korea and were sent back to North Korea, where they suffered all kinds of torture and atrocities in the detention center, and she herself gave herself up to the party secretary to save her boyfriend. However, when she sees no hope of salvation, she goes on a rescue operation to save her acquaintances, her boyfriend, and other North Korean defectors.
They succeed in escaping from the detention center, but while crossing the border, most North Korean defectors fall victim to the merciless shooting of border guards. Only five people survive, but when her boyfriend arrives in China, he is shot and killed by the head of the Border Guard Security Department. Four people safely arrived in South Korea and held a press conference to report North Korea's atrocities of torture and execution.
