하숙 (hasuk) is a traditional Korean lodging arrangement where a landlord rents a room and provides meals — think a family-run bed-and-board. It was the standard way students and young workers lived away from home before modern apartment rentals took over. Eun-sae's comparison stings because it frames them as strangers sharing a roof, not a couple sharing a life.
퇴계 이황 (Toegye Yi Hwang) was a 16th-century Confucian scholar famed for his strict moral principles, and 황희 정승 (Hwang Hee) was a Joseon-era prime minister legendary for his fairness and virtue. Kang-rok is mocking Tae-ha by saying only an impossibly upright historical sage would worry about a guest's sleeping arrangements over his own romantic life.
TMS stands for Transcranial Magnetic Stimulation — a real, non-invasive procedure where a magnetic coil held near the skull sends brief pulses into specific brain regions. It is used in Korea and worldwide for depression and, in research settings, for memory-related conditions. The drama uses it as the medical explanation for why Eun-sae's memories might return in fragments.
지오디 (god) was one of Korea's biggest boy bands of the late 1990s and early 2000s, known for emotional ballads and songs about hardship and family. For someone Eun-sae's age, listening to god on an MP3 player would have been the comfort-music of childhood. The detail quietly confirms when her orphanage years took place and how little she owned.
Reports of criminal groups exploiting Korean state-run orphanages (보육원, boyugwon) — skimming government subsidies and using older children as informal labor — surfaced in real investigations from the 1990s onward. The drama is drawing on this documented social wound to build Eun-sae's backstory, which is why her reaction to violence is visceral rather than abstract.
작두 타기 is one of the most dramatic moments in a Korean 굿 (gut) — a shamanistic ceremony. The 무당 (mudang, shaman) stands barefoot on the upturned blades of a 작두 (chopper) to prove that the spirit has fully entered her body and protects her from harm. Villagers treat a failure to mount the blade as a sign the shaman has lost her spiritual power.
In Korean shamanic tradition a 굿 (gut) ceremony follows strict purity rules. Encountering a snake — associated with ancestral spirits in some regional beliefs — on the day of a ritual is considered a bad omen that voids the ceremony's efficacy. The crowd's instant reaction shows this is a widely shared folk belief, not just the shaman's personal superstition.
스페이스 A (Space A) was a Korean duo whose song '섹시한 남자' ('Sexy Man') was a dancefloor hit in the early 2000s. Singing it here — especially the line about dying of love — is pure dramatic irony: the cheesy lyrics accidentally mirror Tae-ha's real feelings, which is why Eun-sae singing it at him lands as both funny and tender.
읍내 (eumnae) means the town center of a rural county, and a '뚜껑 열리는 나이트' is slang for an old-school nightclub where the energy gets so wild the roof practically blows off — 뚜껑 (lid) literally flies open. These dance halls, once common in small Korean towns, are now a nostalgic punchline representing the aunties' era of big-night-out fun.
Rain carries heavy symbolic weight in Korean culture and popular media — it often marks grief, longing, or turning points in relationships. Tae-ha earlier confessed he hates rain because every lowest moment of his life came with it. Eun-sae turning back precisely because rain is forecast tonight shows she has absorbed his private language and is answering it directly.
