Seri answers the phone with '나예요' (it's me) and calls Jeong-hyeok '리정혁 씨' — the suffix 씨 is a polite but familiar title, roughly 'Mr.' used between equals. Crucially, she drops the ultra-formal speech she used earlier, signalling how close they've become without either of them saying so aloud.
철강 (Cheol-gang) mentions the '11과 특별 대상' — Section 11 of the Bowibu (보위부), the State Security Department that monitors foreign nationals and ideological threats. Being labelled a 'special subject' of Section 11 means Seri is classified as a high-priority surveillance target, which explains why her fate is treated as a state matter rather than a routine arrest.
Cheol-gang taunts Jeong-hyeok with '작년 고랑이 금년 이랑 된다' — 'last year's furrow becomes this year's ridge.' It's an agricultural proverb meaning the tables turn: whoever was on top can end up on the bottom. He's gloating that Jeong-hyeok, once privileged, is now powerless.
The soldiers debate whether a '돈주' (donju, literally 'money master') arranged Seri's kidnapping. Donju are private entrepreneurs who emerged in North Korea after the 1990s famine, accumulating wealth through market trading and lending. They operate outside the state system but often buy influence through bribery, making one plausible as someone who could hire kidnappers.
The men are stunned to learn Jeong-hyeok's father is the 총정치국장 (Chief of the General Political Bureau), the officer responsible for ideological loyalty across the entire Korean People's Army. In North Korea's power structure this post sits just below the Supreme Leader himself, which is why the squad immediately realises their commander's arrest is an explosive political miscalculation.
The man brings Seri 송이버섯차 (songyi mushroom tea), brewed from the prized pine mushroom. Songyi mushrooms grow wild in North Korea's mountains and are one of the country's most valuable export products; offering this tea to a captive is paradoxically a gesture of high hospitality. Seri correctly reads it as a sign that whoever is holding her has significant means.
A classmate tells the young Seo Dan that Jeong-hyeok is preparing for the 차이콥스키 콩쿠르, the International Tchaikovsky Competition held in Moscow. It is one of the most prestigious classical music contests in the world, and a North Korean teenager being groomed for it signals extraordinary talent as well as significant state backing for his musical career.
Jeong-hyeok names the place '이젤트발트' (Iseltwald), a tiny village on the shore of Lake Brienz in Switzerland. It later became famous in South Korea specifically because of this scene, sparking a wave of Korean tourists visiting the wooden jetty shown here. The show is quietly revealing that he and Seri were at the same spot on the same day years before they 'met.'
Seri confesses she had travelled to that Swiss lakeside intending to disappear quietly and die alone. She describes wanting to go somewhere beautiful and not burden anyone — a way of describing passive suicidal ideation common in Korean dramatic storytelling. This reframes their entire first encounter: his unknowing music reached someone at the edge of her life.

Jeong-hyeok recalls joking earlier that after a 파혼 (broken engagement) one should take a six-month mourning period before dating again. He invented the rule to apply to himself, but now uses it as a roundabout way of saying he doesn't want Seri to meet other men too quickly. In Korean social custom, broken engagements carry real emotional and family stigma, so framing recovery time as 'mourning' (애도) plays on that gravity — but here it's also covering up jealousy.
