자장자장 (jajang-jajang) is the Korean equivalent of 'rock-a-bye' — the classic soothing sound parents hum to send a baby to sleep. Kang-hwa is using it as a playful excuse to stay in bed, pretending he's the one being lulled. Yoo-ri's exasperated reaction ('What do you mean, lullaby?!') plays on how absurd it sounds coming from a grown adult who's already late.
Yoo-ri strings together three mild put-down words: 바보 (babo, dummy), 밥팅이 (a playful/dialectal spin on 'rice-brain,' i.e. someone with empty thoughts), and 쪼다 (jjoda, a harmless slang word for a wimp or pushover). In Korean close friendships and couples, piling up these soft insults is actually a sign of deep affection — the harsher-sounding, the fonder the feeling.
Hyun-jeong says Kang-hwa '죽지 못해서 살았다' — literally 'lived because he couldn't die,' meaning he didn't truly want to go on but had no choice. It is a common Korean expression for someone enduring life in total despair rather than actively living it. Hearing that Yoo-ri witnessed all of that grief is exactly why Hyun-jeong kept the truth from him.
Kang-hwa's father-in-law mentions that Kang-hwa came to 'get permission' before remarrying. In Korea it is considered respectful — and emotionally necessary — to visit the late spouse's parents and formally ask their blessing before entering a new marriage. Skipping this step would be seen as disrespectful to the memory of the deceased and hurtful to her family.
퇴마사 (toegmasa) literally means 'exorcism master' — a person who drives out evil spirits. Unlike the Catholic priest of Western exorcism films, a Korean 퇴마사 sits somewhere between a shamanistic practitioner and a ghost-hunter in popular culture. The character Yoo-ri is furious about is one of these figures, who has been tracking her daughter because the child can see the spirit world.
Eun-suk tells Yoo-ri she visits the temple to thank the Buddha for sending her daughter back and to make sure she keeps showing up so the blessing isn't taken away. In Korean folk-Buddhist practice, parents often make regular visits to pray for the wellbeing — or the peaceful passing — of a loved one, and gratitude offerings are considered just as important as petitions.
Geun-sang sings '내게 강 같은 평화' (Peace Like a River), a well-known Protestant praise song sung in Korean churches. He belts it out loudly in public to steady his nerves after being spooked — a comedic but very Korean reflex, where familiar church music acts as an instant emotional anchor for many believers.
맘 카페 (mom café) refers to the hugely popular online communities — hosted mainly on the Naver Café platform — where mothers in the same apartment complex or neighbourhood share parenting tips, school gossip, and local news. Hyun-jeong is teasing the women for treating her restaurant like a cosy hangout in the same way they treat those forums: a place to share gossip and bond over neighbourhood drama.
아지트 (ajiteu) is borrowed from the Russian word 'agitpunkt' but in everyday Korean it simply means a cosy hideout or members-only hangout spot — the kind of place only your inner circle knows about. Min-jeong using the word signals that the restaurant has become something genuinely rare for her: a safe, familiar place in a neighbourhood where she long felt like an outsider.
Kang-hwa calls Cha Yoo-ri's name a 금기어 (geumgi-eo), a 'forbidden word' — something so painful it cannot be spoken aloud. In Korean emotional culture, naming grief directly is often avoided; a name becomes unspeakable when the wound around it is still raw. Min-jeong asking him to finally open that 'room' is a request to stop carrying the grief alone and let her share it.
'소나무' (Sonamu, The Pine Tree) is a beloved Korean folk song taught to children in school and often sung as a lullaby. The pine tree is a classic symbol of steadfast loyalty and endurance through hardship in Korean culture — it stays green no matter the season. Yoo-ri asking her mother to sing it on what may be one of their last nights together gives the song a quietly devastating weight.
칠렐레팔렐레 (chil-lel-le pal-lel-le) is a playful, onomatopoeic Korean expression describing someone who is skipping along without a care, blissfully oblivious — roughly 'traipsing around la-la-la.' Min-jeong uses it self-mockingly to describe how openly, naively happy she was while Yoo-ri was watching — which makes the moment both sweet and heartbreaking.
Hyun-jeong sets up the contrast between '죽고 싶다' (I want to die) and the final line '나도 살고 싶다' (I want to live, too). In Korean grief language, these are mirror phrases. The episode's title is 'A Story I Could Not See,' and the closing line flips the series' central wound: after five years of watching Kang-hwa barely surviving, Yoo-ri arrives at the desire not to hold on, but to let both of them truly live.
