Earlier in the series we learned that Seon-woo has a set of special incense sticks from the Himalayas that let him travel back exactly 20 years in time. Each stick can only be used once, so every burn is irreversible — which is why Yeong-hun urgently tells him to save one stick rather than use them all up.
The priest's words are the formal consent rite from a Catholic wedding Mass (혼인성사, hon-in seong-sa). Korea has a significant Catholic minority, and church weddings carry strong social prestige. The solemn liturgical language underlines that this union — and the family it creates — is meant to be permanent in the eyes of the community.
From the 1970s through the 1990s, emigrating to the United States (이민, i-min) was a major aspiration for middle-class Korean families seeking better opportunities. Children who moved abroad often lost touch with friends and relatives left behind, which explains why young Seon-woo, hearing this news mid-ceremony, looks so unsettled.
개명 (gaemyeong) — legally changing one's name — was once rare and required a court order in Korea. A child changing her name after a parent remarried was unusual enough to be memorable, which is exactly why Seon-woo never connected adult Min-yeong (her new name) to the little girl he once met as Si-a.
Christmas is a public holiday in Korea and one of the biggest dates in the Catholic and Protestant calendars. Midnight Mass (미사, mi-sa) draws large crowds, and churches are open for services throughout Christmas Day. Yeong-hun coming to the cathedral reflects how deeply embedded the holiday is in Korean city life, even for people who are not regular churchgoers.
라마교 (Ra-ma-gyo) is the Korean term for Vajrayana Buddhism as practiced in the Himalayan region — what Westerners often call Tibetan or Lamaist Buddhism. Seon-woo's joke is that because the magical incense came from a Himalayan monastery of that tradition, Yeong-hun should be praying at a Buddhist temple, not a Catholic church.
In Korea, 크리스마스이브 (Christmas Eve) is primarily a couples' holiday — closer in feel to Valentine's Day than a family celebration. Restaurants and cafés are fully booked weeks in advance, and being alone on Christmas Eve carries a social stigma that makes Yeong-hun's joke about Seon-woo 'going hunting' (헌팅, picking someone up) land harder than it might otherwise.
소개팅 (so-gae-ting) is a one-on-one blind date arranged by a mutual acquaintance, distinct from group meetings. A key unspoken rule is that the matchmaker steps back completely once introductions are made — 'no post-date management' is practically a social code. Yeong-hun quoting his own rule immediately after engineering the meeting shows he is well aware he is violating the spirit of it.
비아그라 (bi-a-geu-ra) is Viagra, the erectile-dysfunction drug. Seon-woo claims he overdosed on it as a prank explanation for collapsing — the absurdity is that a single man in his thirties supposedly went 'hunting' on Christmas Eve and ended up in his own bed unconscious instead. Korean comedy often uses frank medication references for deflating embarrassment.
포카라 (Pokhara) is a lakeside city in Nepal and the gateway to the Annapurna trekking region. 페와 호 (Phewa Lake) sits at its heart, reflecting the iconic fishtail peak 마차푸차레 (Machapuchare, 6,993 m). Machapuchare is sacred to Hindus and has never been officially summited, which gives it an almost mythical status among trekkers — exactly the romance Min-yeong is describing.
The scene gathering at what appears to be a family memorial table references 제사 (je-sa), the Confucian ritual held on the anniversary of an ancestor's death. Food and drink are set out, incense is burned, and family members bow — the 'coming alone' Seon-woo mentions suggests he has been the sole person attending his mother's 제사 for years, making tonight's larger gathering emotionally significant.
Korean dramas frequently frame a serious illness with a doctor's estimated runway — here 'about three months.' This sets up a classic dramatic clock: the audience knows roughly how long the character has, and any sudden acceleration of symptoms signals the story is entering its final act. The tension here is that Seon-woo feels the decline happening far faster than predicted.
