Iblис explains why he was cast out — he refused to bow to Adam, who was made of clay (흙덩이, heuk-ddeong-i, literally 'lump of earth'). This is straight from the Quran (Al-Baqarah 2:34), where the angel/jinn Iblis alone refuses God's command to prostrate before the first human. It's the origin story the drama is pulling from, so when he says 'lump of clay' as an insult, it carries thousands of years of religious grudge.
The show lays out three names for the same being: 이블리스 (Iblис, from Arabic إبليس), 샤이탄 (Shaitan, from Arabic شيطان, meaning 'devil'), and the word familiar to most viewers — 사탄 (Satan). In Islamic cosmology Iblis is a jinn, not a fallen angel, which is why the drama frames him as the most dangerous kind of genie rather than simply a demon from a Western tradition.
안중근 (Ahn Jung-geun, 1879–1910) is one of Korea's most revered independence heroes. He assassinated Itō Hirobumi, the Japanese Resident-General of Korea, at Harbin railway station in 1909 and was executed by Japan the following year. Koreans learn about him from childhood, so Iblis popping up in that exact moment — among Ahn's comrades the night before a mission — signals the scene is set in the final, dangerous weeks of the resistance.
효수 (hyosu) was a punishment in the Joseon dynasty where a criminal was beheaded and their head displayed on a pole at the city gate as a public warning. King Seonjo orders it without a second thought, which was historically plausible during wartime. The comic payoff — Iblis's severed head keeps calling 'Ga-young!' for three days — is the drama riffing on actual Joseon-era 야사 (yasa), unofficial folk histories that circulated alongside official records.
Changsik mentions that men in the Middle East press noses together (코 뽀뽀) as a gesture of deep respect for an honoured guest. This is real — a nose-to-nose or forehead-to-nose touch is a traditional greeting in Gulf Arab and some Central Asian cultures, reserved for close friends, elders, or distinguished visitors. The drama drops it here as a warm cultural bridge moment, since Iblis is portrayed as coming from a Middle Eastern mythological tradition.
Im-seon's wish zeroes in on a real Korean workplace sore point: the gap between 정규직 (jeonggyu-jik, permanent/regular employees) and 비정규직 (temporary or part-time workers). Large Korean supermarkets often employ floor staff on short-term contracts with far fewer rights and lower pay than salaried staff, even when those workers have decades of experience. Her frustration that a younger, university-educated woman outranks her despite Im-seon's 20 years on the floor rings true to many Korean viewers.
Ga-young's punchline is a pun: the digit 4 is pronounced 사 (sa) in Korean, which sounds identical to 死 (sa, meaning death). This is why many Korean (and other East Asian) buildings skip the 4th floor, hospitals avoid room 4, and some people are genuinely uneasy about anything involving the number. The fact that the car-shop owner closes on the 4th, 14th, and 24th of every month — days all containing 사 — is Ga-young reading it as a death-themed ritual.
감자탕 (gamjatang) is a hearty Korean stew made with pork neck bones, potatoes (감자), and fermented kimchi or doenjang — it's filling, cheap, and a beloved comfort meal, especially eaten late at night. The reveal that the car-shop owner keeps a fixed Wednesday gamjatang date connects back to a person introduced earlier in the episode, turning an ordinary comfort-food habit into a meaningful character clue.
사주 (saju, 四柱) is the Korean system of fortune-telling based on the year, month, day, and hour of a person's birth — the 'four pillars.' Grandma Pan-geum instinctively asks for Iblis's birth data to size him up as a match for Ga-young, which is very common: Korean families still consult a 사주쟁이 (fortune reader) before big life decisions like marriage. Iblis answering 'Thursday, 13.8 billion BC' is the joke — his 'birthday' is the Big Bang.
The rooftop star-gazing scene draws on a well-known Seoul dating tradition: couples visit the Han River (한강) parks or high rooftop spots at night to watch the city lights and, famously, eat 치킨 (fried chicken) and 라면 (instant noodles) from nearby convenience stores. 'No pushing this time' is an internal joke, but the setting — urban darkness sought out for a private, romantic moment — is a recognisable shorthand for Korean rom-com intimacy.
'너로 가득 찬 밤' (Neoro Gadeuk Chan Bam, 'A Night Full of You') is the original soundtrack ballad that plays over the episode's first kiss. Korean dramas treat the OST drop as a formal emotional punctuation mark — when the full song swells, viewers know the scene is the emotional peak the episode has been building toward. The song is performed by 수지 (Suzy) and 소수빈 (So Soo-bin), both well-known in the Korean pop and drama world.
