Sleepwalking & binge eating (잠결에 폭식)
3:04
Disordered eating
Shi-ho brushes off the midnight fridge incident by saying she developed a habit of binge-eating in her sleep — 잠결에 폭식 (jamgyeore pokshik). For Korean athletes who severely restrict calories to make weight, secret late-night eating (and even sleepwalking to the kitchen) is a real and talked-about side effect of extreme dieting.

Sleeping pill side effects in Korea
4:26
The doctor lists 몽유증상 (mongyoo jeungssang) — sleepwalking — as a late-stage side effect of sleeping pills. Prescription sleep medication is tightly regulated in Korea, but misuse among high-pressure athletes and students is a documented public-health concern that Korean audiences would recognise immediately.

Weight-class cutting (감량) in weightlifting
7:28
The coach tells athletes who were 감량-ing — cutting weight to meet a competition weight class — that they can eat freely during the break because they need to rebuild muscle. In Korean weightlifting culture, severe pre-competition cuts followed by a deliberate eating-and-recovery period are a standard part of the training cycle.
#
버킷리스트 (Bucket List) culture
11:59
The on-screen graphic shows Bok-joo's handwritten 버킷리스트 — the Korean word is borrowed straight from English. Making personal bucket lists, especially for ordinary everyday pleasures rather than grand adventures, became a big social trend in Korea in the 2010s and is a recurring motif in youth dramas of this era.
#
Amusement-park headbands (머리띠)
14:22
Buying a novelty headband — animal ears, devil horns, halos — the moment you walk into a Korean amusement park is basically a rite of passage. Places like Everland and Lotte World sell them at every entrance shop, and wearing matching 커플 (couple) headbands is a classic date-day move that Korean visitors of all ages do without irony.
#
바이킹 (Viking) ride
15:41
The ride they're screaming on is called 바이킹 (Baeiking) — the giant pirate-ship pendulum that swings back and forth. It's one of the 'Big 5' classic rides at Korean theme parks and has been a staple since the 1980s. Arguing about which end seat gives the biggest thrill is a national pastime.
#
츄러스 (Churros) as Korean theme-park food
18:20
Churros became the signature snack food of Korean amusement parks in the 2000s and are now inseparable from the experience — the way popcorn is tied to cinemas. Sharing one cola with two straws is a small but loaded romantic gesture that Joon-hyung is very deliberately engineering.
#
모텔 (Motel) culture in Korea
24:48
Mature
Sun-ok's family runs the front desk of a 모텔 — a short-stay motel. Korean 모텔 chains (often with neon signs and room rentals by the hour, called 대실/daesil) are extremely common and carry a certain social stigma; growing up behind that counter, as Sun-ok did, is something she's clearly ashamed of.
#
대실 vs 숙박 (Hourly vs overnight stays)
25:39
Mature
The receptionist asks whether Joon-hyung wants 대실 (daesil — a few hours) or 숙박 (sukbak — overnight). Korean motels price these separately; 대실 is the cheaper daytime option. The awkward look on Bok-joo's face makes sense — she's standing in the lobby of her friend's family's motel while a guy she knows is checking in.
#
혈액투석 (Haemodialysis)
29:45
The sign reads 혈액투석실 — the haemodialysis ward. Patients with serious kidney failure in Korea typically come to hospital several times a week for multi-hour dialysis sessions. The fact that Bok-joo's father has been doing this long enough for the effectiveness to drop explains the doctor's push toward a transplant (이식).
#
복치킨 (Bok Chicken) — the family shop
43:03
The family business is a 치킨집 (chikin-jip) — a fried chicken shop — called 복치킨. Neighbourhood chicken shops are one of the most common small family businesses in Korea; they are beloved, fiercely competitive, and often represent a parent's entire life savings and labour. The closed sign hits differently knowing that's the case here.
#
보험 증서 (Insurance policies)
44:02
Self-harm
Bok-joo finds a stack of 보험 증서 — insurance policy documents. It is extremely common in Korean family culture for parents, especially single parents, to quietly stack up life insurance policies for their children without telling them. Finding them is a gut-punch moment because it shows the father has been planning for a future without himself in it.
This note discusses suicide or
self-injury. If you need someone to talk to: in Korea call 109,
in the US call or text 988, or
find a helpline in your country.
#
Military-style reporting (신고합니다 / 충성)
48:45
Bok-joo snaps to attention and delivers a formal return-to-duty report ending in 충성! (loyalty/salute). Korean university sports programs, especially at athletic colleges, run with a quasi-military structure — players report to coaches using military language, stand at attention, and formally announce arrivals and departures. It's played partly for laughs here but it's an accurate reflection of the culture.
#
'반품' (Return/refund) as a confession metaphor
57:48
Bok-joo tells Joon-hyung she won't 반품 him — literally 'return the goods' for a refund, the way you'd send back an online purchase. It's a playful callback to his earlier 'free trial experience' bit, but flipping his shopping metaphor into a genuine confession is a very Korean drama move: wrapping real feelings in silly slang so they're easier to say out loud.
