Matthew introduces himself using his Korean name, 강성민 (Kang Seong-min), and explains he was found at a train station in Chuncheon, Gangwon Province — a detail that would appear on an abandoned child's official record. Babies found without identification in Korea were named and registered by the receiving institution, which is why his Korean name was given to him by strangers rather than by family.
The document reading 'Deportation' reflects a real legal gap: thousands of Korean children sent abroad before the late 1990s were never automatically granted citizenship in their adoptive country. If adoptive parents didn't file the paperwork — or if the adoption broke down (파양, pa-yang) — the child could end up with no nationality at all, making them subject to deportation from both countries.
The anchor's broadcast marks the 25th anniversary of the 삼풍백화점 참사 (Sampoong Baekwha-jeom Chamsa), the 1995 collapse of a Seoul department store that killed 502 people — one of the deadliest peacetime building disasters in history. It became a defining symbol in Korea of the human cost of cutting corners on safety and ignoring warnings, and anniversaries are still covered seriously in Korean news.
Korea began sending children abroad for adoption in the 1950s after the Korean War and continued on a massive scale for decades, eventually earning the painful label '고아 수출국' (goa suchulguk) — 'orphan-exporting nation.' By the time this episode is set, well over 150,000 children had been sent overseas, and support groups helping adoptees search for birth families had become a recognised part of Korean civil society.
파양 (pa-yang) is the legal cancellation of an adoption. In Korean law and in the laws of several adoptive countries, a dissolved adoption could strip a child of the legal status they had in the adoptive family, including any path to citizenship that adoption had opened. For children like Matthew who were already abroad, this could leave them in a legal no-man's land with no nationality.
나무 identifies the tiny garment as a 배냇저고리 (baenaet-jeogori), the traditional first outfit a Korean baby wears in the hours after birth. The word combines 배내 (in the womb) with 저고리 (a Korean jacket). Mothers often keep it as a keepsake for life, so the fact that Matthew — not his mother — held onto it quietly signals how completely he was cut off from his origins.
Eun-jeong explains that her mother worked as a 위탁모 (witakmo), a foster mother who cared for infants in a 위탁 가정 (witak gajong — foster home) while they waited to be flown overseas. This was a standard part of the intercountry adoption pipeline in Korea: babies stayed with paid foster families for weeks or months between leaving their birth mothers and boarding the plane.
Gru says he found the match by locating 'the same face in a book' — he compared the torn photograph in Matthew's belongings against a reference book, likely a broadcaster directory or yearbook (방송인 연감), which Korean broadcasting companies publish annually with staff photos. This kind of printed directory is a practical tool that predates easy internet image searching in Korea.
Eun-jeong's broadcast cites roughly 200,000 Korean children sent abroad over 65 years — a figure widely quoted by researchers and advocacy groups. South Korea held the record for the highest number of intercountry adoptions for several decades, a source of ongoing national shame and debate. The broadcast frames this as context for Matthew's death, turning a private tragedy into public accountability.
Gru quietly reveals he too was adopted — he does not know his birth parents, just like Matthew. The difference, he says, is that he found his father (Jeong-u's dad, Han Jeong-u), who named him 한그루 (Han Geu-ru) and loved him. In Korean culture, being given a name by a parent is a profound act of claiming someone as your own; the contrast with Matthew, who kept the institutional name 강성민 on torn paper, is deliberate and tender.
Gru explains 펀치 드렁크 신드롬, now more commonly called Chronic Traumatic Encephalopathy (CTE) — brain damage that builds up from repeated blows to the head. In Korean professional boxing circles, fighters sometimes continue competing long after doctors would advise stopping, either for money or because leaving the ring means losing the only identity they have. Namu's alarm suggests she believes Sang-gu already knows he is damaged and is fighting anyway.
