Bong-soon's mom wants to check 궁합 (gunghap) — a traditional compatibility reading based on two people's birth years, months, days, and birth hours according to the lunar calendar. Consulting a fortune teller about a potential couple's 궁합 before a relationship gets serious is still very common in Korea, even among younger families. The birth hour detail she keeps pressing for matters because the full 사주 (sajoo), or 'four pillars,' requires all of it.
Both Min-hyuk and Gook-doo call themselves 'Romeo' while Bong-soon is cast as 'Juliet' — but the joke in Korean rom-com logic is that Bong-soon is actually the physically dominant one, so she would more naturally be the hero rescuing the prince. The drama is very deliberate about flipping gender-role clichés, so the Romeo/Juliet debate is both a love-triangle gag and a wink at that theme.
Oh Dol-bae piling impossible tasks on Bong-soon — a same-day report and ten heavy boxes — reflects the 선배/후배 (sunbae/hoobae) senior–junior culture in Korean offices. A hoobae is expected to comply without complaint, and openly pushing back is considered rude. Bong-soon's careful, roundabout protests ('What if I do the boxes tomorrow since the report is urgent?') are her trying to stay within that etiquette while resisting.
Min-hyuk buys a necklace whose name means 'A Wish Sent to the Moon.' Moon imagery is deeply romantic in Korean culture — sending a wish to the moon is a classic poetic gesture tied to folk customs like making wishes at 정월대보름 (the first full moon of the lunar new year). Choosing a gift with this built-in meaning rather than just picking something pretty signals that he is thinking carefully about symbolism.
The office buzz is that Min-hyuk 'came out' at the seminar, which panics the staff — until someone clarifies that he publicly announced he likes women. In Korean, 커밍아웃 (keoming-aut) has been adopted from English and is used almost exclusively for coming out as LGBTQ+, so the gap between expectation and reality is the joke. The scene pokes gentle fun at the word's connotation without malice.
Min-hyuk's pitch describes a global shift from battle-style to 'explore' games where the real world and the game world connect — a clear nod to the Pokémon GO craze that swept Korea in 2016, right when this drama was made. His aside about someone sneaking into a military restricted zone to catch a character was a real incident that made national news in Korea at the time, grounding the joke in a very specific cultural memory.
Gook-doo's line about their timing always being off is a cornerstone sentiment in Korean melodrama and pop music — the idea that two people who are right for each other simply arrive at the wrong moment is called 타이밍 문제 (timing problem) and appears in countless songs and films. Saying 'our timing is always like this' is a culturally recognized way of closing a chapter without blame, which makes the goodbye land harder.
The students demand to know who the 오야 (oya) is — a Korean underworld and gang slang term borrowed from the Japanese 親 (oya, meaning 'parent' or 'boss'). It refers to the top figure of a local criminal crew. Using this word marks the students as wannabe toughs trying to sound like serious gang members, which is part of the comedy since they are university boys looking for Bong-soon's attacker.
Baek-tak compares himself to the Silla-dynasty Buddhist monk 원효대사 (Wonhyo Daesa), who according to legend drank water from what he thought was a clean bowl in the dark, felt refreshed, then discovered in daylight it was a skull full of stagnant water — and had a great enlightenment about how the mind shapes reality. It is one of the most quoted parables in Korean Buddhism and everyday speech. Baek-tak using it to justify his own 'enlightenment' via a bottle of sewage is the gag.
