The coach grumbles that the students are "sucking and licking" instead of training — a colorful Korean expression of disgust at couples being openly affectionate in public. In Korea, especially at sports academies where discipline is prized, public displays of affection on campus are frowned upon by older authority figures, who see it as disrespectful to the training environment.
The phrase 눈에서 꿀이 떨어진다 — literally "honey drips from the eyes" — is a common Korean idiom meaning someone is so lovesick or smitten that you can see it written all over their face. It's the equivalent of saying someone is wearing their heart on their sleeve.
Nan-hee has whipped up a homemade 팩 (face mask) from flour, potato, and honey — inexpensive kitchen staples widely used in Korean home beauty routines. K-beauty sheet masks and DIY skin-care treatments are a normal part of dorm life for young women, often turned into a bonding activity with friends.
Nan-hee quotes the proverb 금강산도 식후경 — "Even the beauty of Mt. Geumgang comes after a meal" — meaning you can't enjoy or focus on anything properly when you're hungry. It's one of the most-used Korean sayings and is wheeled out whenever someone insists on eating before doing anything else.
Sung-eun jokes about whether she should have prepared a 구첩반상 — a traditional Korean royal-court-style meal with nine separate side-dish bowls arranged symmetrically around a bowl of rice. It is the most elaborate tier of the traditional 반상 (table setting) system and is now shorthand for an over-the-top home-cooked spread.
When the friends demand a 신고식 from Joon-hyung, they're invoking a real Korean social custom: a newcomer — whether a new team member, a new boyfriend entering a friend group, or a new colleague — is expected to 한턱 쏘다 (treat everyone) to food or drinks as their official "entry fee." It signals he accepts his place in the group and is done in good humor.
The commentator mentions 후프 (hoop), 곤봉 (clubs), and 리본 (ribbon) — three of the five hand apparatus used in rhythmic gymnastics competition. Athletes compete in separate routines with each apparatus, and a single loss of control — such as the ribbon prop sailing over the boundary line — triggers immediate deductions, making perfect apparatus handling crucial.
One of the gymnasts bitterly mutters that only people without 코치빽 — literally "coach backing," meaning an influential coach or connection — get penalized properly. The complaint echoes a widespread real-world concern in Korean amateur sports that athletes from well-connected programs receive more lenient judging than independents.
Jae-yi's dad teases his wife that she should just 돗자리 깔다 — "spread a floor mat" — a playful jab meaning she might as well set up as a fortune-teller (점쟁이) given how confidently she reads people's feelings. Street fortune-tellers in Korea traditionally sit on mats outdoors, so the phrase conjures that image.
The woman asking "Do you recognise me?" and then identifying herself as Joon-hyung's mother is a significant moment in the context of Korean family drama. In Korean culture, a parent who has been absent for years — especially a mother — carries heavy social stigma, and their sudden return is laden with obligation, guilt, and unresolved han (한), a deep-seated feeling of grief and resentment.
