In Korean boxing, a coach throwing a towel (수건을 던지다) into the ring is the official way to forfeit a match on behalf of a fighter — identical to the English phrase 'throwing in the towel.' What makes this flashback shocking is that Sang-gil was *winning*, so his coach's surrender is a deliberate punishment, not a protective act.
씨발 (ssi-bal) is one of the harshest all-purpose expletives in Korean, roughly equivalent to the English f-word. Young Sang-gil hurls it in raw frustration after being publicly expelled by his coach — the word signals he has completely lost his composure.
엿 is a traditional Korean taffy-like candy made from glutinous rice or sweet potatoes, pulled into long golden strands. The village Eun-sae has been hiding in is nicknamed '엿마을' (Yeot Village) because it's known for making it — the bag of yeot she brings is a local souvenir that doubles as a clue about where she's been.
The song playing over the village women missing Eun-sae is '그리움만 쌓이네' (Only Longing Piles Up) by ballad singer 노영심 (Noh Young-sim), released in 1989. It became a beloved classic about missing someone who has left, so hearing it here while the women reminisce is a very deliberate emotional cue that any Korean viewer over 30 would feel instantly.
'연분홍 장미' (Light Pink Rose) is another classic Korean pop song, associated with karaoke nostalgia. The women have apparently been gathering at the 노래방 (norebang — a private karaoke room) to sing together, and this song in particular sparks laughter, suggesting it was Eun-sae's go-to number.
율무차 (yuulmu-cha) is a warm, milky tea brewed from Job's tears — a grain that looks like small ivory beads. It has a mild, earthy flavour and is associated with health benefits in Korean food culture. Ki-jun confesses he kept ordering it at the café despite not liking it just so he'd have a reason to see Su-ji — making the humble drink a small monument to his younger self's crush.
오골계 (ogolge) is a black-boned silkie chicken prized in Korean medicinal food culture for restoring strength after illness or injury. Eun-sae serves it specifically for Tae-ha's recovery, then jokes that it's wasted on Kang-rok because it's traditionally considered most beneficial for people in their 30s and older — a classic Korean food-as-medicine mindset.
SES (에스이에스) was one of Korea's first major K-pop girl groups, debuting in 1997 under SM Entertainment with members Bada, Eugene, and Shoo. Kang-rok name-drops them as a comic way of saying Eun-sae has plenty of people she could stay with — the reference works because the group is so iconic that even younger Koreans recognise it instantly.
Baek Sang-gil returns to what appears to be the same small drinking spot he visited decades ago — a familiar Korean trope of the neighbourhood 술집 (suljip, drinking house) that outlasts everything around it. The owner's matter-of-fact memory of how many bottles he drank that night reflects the Korean drinking-bar culture where a regular's habits are simply remembered, no judgment attached.
좆같다 (jot-gat-da) is a crude Korean expletive — literally referencing male genitalia — used to mean 'it felt absolutely terrible / like total shit.' Sang-gil uses it speaking candidly to the bar owner, a level of bluntness that signals they have the easy familiarity of a long-standing local relationship rather than a formal one.
은새 (Eun-sae) peels back a 찍찍이 (jjikjjigi — the Korean onomatopoeic word for Velcro) panel inside her shoe to retrieve a hidden memory chip. Concealing evidence inside everyday clothing is a real technique referenced in Korean legal dramas; the squealing Velcro sound effect makes the discovery feel both mundane and momentous.
Do-yeop's raw, full-voiced wailing as he searches for Jeong-hwa reflects the Korean concept of 통곡 (tongok) — unrestrained public mourning that is culturally accepted and even expected when grief is overwhelming. Unlike many Western screen portrayals of stoic grief, Korean drama (and real life) treats this kind of open crying as honest and deeply human, not embarrassing.
