When Detective Yuk declares the case closed, his first instinct is to take the team out for 삼겹살 (grilled pork belly) and 소주 (soju). In Korean workplace culture, finishing a tough job calls for exactly this combination — it's the default 'we made it' meal, especially among colleagues who've been pulling all-nighters.
Bong-ki cracks open a can of beer (맥주) while chatting with his dad late at night — a totally normal scene in Korean homes where convenience-store beer is cheap and drinking casually with family is unremarkable. The relaxed atmosphere makes the emotionally heavy conversation that follows feel more real.
Bong-ki reveals he chose medical school specifically to study his family's hereditary super-strength — not for prestige or money. In Korea, getting into 의대 (medical school) is one of the most competitive and respected achievements possible, so saying he had a personal, secret reason behind it adds real weight to the confession.
Jin-yi rushes out to buy 꼬리 (oxtail) and meat to cook for the traumatized Gyeong-sim. 꼬리곰탕 (oxtail bone broth soup) is a classic Korean restorative dish — slow-cooked for hours until the collagen-rich broth turns milky white. Mothers and grandmothers make it when someone needs to rebuild their strength after illness or hardship.
Bong-soon tells Gyeong-sim she had been secretly setting aside part of her paycheck to buy her a dress. The verb 꼬불치다 means to quietly hide or stash money away, usually from a shared pot or one's own wages, without telling anyone. It's a very colloquial, affectionate expression — the kind of thing a close friend does as a surprise.
Jin-yi tells Bong-soon that after she herself lost her powers, the first thing she did was go back to lifting the lightest dumbbells — 역기 (barbells/weights). Rather than mourn what was gone, she rebuilt her daily routine from scratch. This advice mirrors a broadly Korean cultural value: 일상으로 돌아가는 것 (returning to ordinary life) as the most practical form of healing.
Min-hyuk suggests they finally go on a normal, low-key date now that the danger is over. The word 평범하다 (to be ordinary/average) has been used throughout the series as something Bong-soon longed for. His using it here is a quiet acknowledgment that her wish — to live like everyone else — is now within reach.
Min-hyuk insists Bong-soon call him 오빠 — the term a younger woman uses for an older male friend or boyfriend in Korean. Even though they turn out to be the same age (동갑), couples in Korea often still use 오빠 as a term of endearment. Bong-soon's refusal and then playful use of his bare name signals a shift toward a more equal, teasing dynamic between them.
The Indian monk Nizamuddin raves about the 소고기 미역국 at the bathhouse — beef and seaweed soup. This dish is one of the most iconic in Korean food culture: it's eaten on birthdays (because mothers eat it after giving birth) and is considered deeply nourishing. His enthusiasm for it while in a Korean 목욕탕 (public bath) plays up the comedy of a foreign monk going fully native.
Detective Yuk wraps up the investigation by announcing everyone is heading to a 삼겹살집 (grilled pork belly restaurant) for 소주. This is a deeply ingrained ritual in Korean work culture — the hoesik (회식), or team dinner, marks the end of a shared ordeal. Choosing 삼겹살 over something fancier signals the team's down-to-earth bond.
Jang-hyeon references Bong-soon's earlier forced 'promise' to marry him — a trope in Korean thrillers where the villain frames his crimes as a twisted form of courtship. The idea that breaking a promise (약속) demands a fatal consequence is used here to underline just how delusional and dangerous he has become.
Trapped with a ticking bomb and Min-hyuk outside the locked door, Bong-soon drops to her knees and pleads for her supernatural strength to come back so she can save him. The 역량기 (Power Notebook) graphic appears again — the show's visual shorthand for her abilities activating. Her prayer echoes the Confucian and folk-religious idea that sincere desperation can move heaven.
With her strength miraculously restored, Bong-soon throws herself at the bomb just before it detonates. The explosion happens off-screen rather than as spectacle — a common choice in Korean romantic dramas where the emotional payoff (the couple surviving) matters more than action-movie visuals. The scene closes the season-long arc of her feeling like a burden without her powers.
