수면제 (sumyeonje) means sleeping pills. In Korea, sleeping pills are prescription-only and carry a real stigma — many people try to manage insomnia privately rather than seeking help. The doctor's mention of sleepwalking and memory loss as side effects quietly signals that Song Si-ho's strange nighttime behaviour isn't supernatural, which is what the dormitory ghost rumours have been about.
오지랖 literally means the front flap of a traditional robe that overlaps too far — it became slang for someone who sticks their nose into things that aren't their concern. Telling Bok-joo her 오지랖 is wide while her own situation is a mess ('네 코가 석자' — your own snot is three feet long, i.e. fix yourself first) is a classic Korean double-put-down, but Bok-joo keeps worrying anyway.
University sports teams in Korea live in strict residential training programmes where leaving campus requires permission. 특박 (特泊) means a special authorised stay outside the dormitory, usually granted around holidays or before intensive training blocks. Getting 특박 is genuinely exciting — it is a rare taste of normal student life.
The on-screen caption 'Bok-ju's Bucket List #3 — Go to an amusement park on a weekday and ride the Big 5 without queuing' shows that the drama is treating her list as a running gag and character shorthand. Weekdays are prized because Korean theme parks like Everland and Lotte World are famously packed on weekends and public holidays — going mid-week genuinely means almost no lines.
The on-screen caption interrupts itself mid-sentence: 'Bok-ju's Bucket List #4 — Get a boyfriend…' This is the show's cheeky way of flagging that Joon-hyung sharing one cola with two straws is accidentally ticking that box. In Korean dating culture, sharing one drink with two straws (빨대 두 개, two straws) is a recognised rom-com shorthand for 'we are basically a couple now.'
짝사랑 (jjak-sarang) means unrequited or one-sided love, and it carries a particular weight in Korean culture — there is almost an expectation that a good friend silently carries these feelings rather than disrupting the friendship. Ah-young finally naming hers after ten years and calling it 희망고문 (hope-torture — the agony of false hope) is a recognised term for when someone lets you believe there might be a chance without ever confirming it.
The long mutual apology between Bok-joo and her father, including small childhood grievances like leaving his kimbap uneaten on a school field trip, is very typical of Korean family melodrama catharsis scenes — all the unsaid things come out at once. His apology for her never getting to say '엄마' (mum) to anyone acknowledges that in Korean culture, a single father raising a daughter alone carries a specific, heavy social guilt.
Bok-joo says she won't 반품 (ban-pum) him — literally 'return goods to the shop,' a consumer-culture word repurposed as a confession. It's deliberately clumsy and un-romantic, which is completely in character. Following it up with 'whether as a friend or as a guy, I want you next to me' is the Korean drama version of working up to 'I like you' without actually using the standard confession formula 좋아해 until the very next breath.
