Kim Yoo-jung: Biography, Relationships, Health and Career Facts

Kim Yoo-jung has been a familiar face on Korean screens since she was a child — but behind the millions of Instagram followers and award-winning roles lies a story that’s often mixed with rumor. This article separates the facts from the fiction, from her early days as a model to her upcoming drama in 2025, based on verified sources, not social media chatter.

Birthdate: September 22, 1999 · Birthplace: Seoul, South Korea · Instagram Followers: 15 million · Notable Nicknames: Nation’s Little Sister, Sageuk Fairy · Agency: Awesome ENT · Height: 162 cm (AsianWiki data)

Eight core facts about Kim Yoo-jung, all backed by public records and entertainment databases.

What is the relationship between Park Bogum and Kim Yoo-jung?

Park Bo-gum’s dating history

Park Bo-gum has never publicly confirmed a romantic relationship. As of 2025, his dating history remains unverified by any official source (MyDramaList). The two actors co-starred in the 2016 hit drama Love in the Moonlight, which sparked widespread dating rumors among fans. However, neither party has ever confirmed a real-life romance.

Kim Yoo-jung’s confirmed relationships

Kim Yoo-jung has not publicly dated any co-star. The only relationship documented is a childhood friendship with actor Yeo Jin-goo, which remains platonic (YouTube – The Untold Story of Actress Kim Yoo Jung). All other pairing rumors — including with Park Bo-gum — are fan speculation.

The pattern: co-star chemistry often fuels romantic rumors, but both actors have consistently chosen to keep their private lives separate from public roles.

Did Song Kang and Kim Yoo-jung date in real life?

On-screen chemistry vs. off-screen reality

In January 2025, search data shows no known relationship between Song Kang and Kim Yoo-jung. Neither actor has issued any statement confirming a romantic link (MyDramaList). Their collaboration in the drama My Roommate is a Gumiho (2021) was strictly professional, according to production sources.

The catch: when a drama is as popular as My Roommate is a Gumiho, the public often conflates fictional romance with real life, but the actors’ professional boundaries tell the true story.

What happened to Kim Yoo-jung?

Collapse during filming

In 2012, while filming The Moon Embracing the Sun — a drama that achieved over 40% ratings (Wikipedia) — Kim Yoo-jung collapsed on set due to exhaustion. She was 12 years old at the time and had been working long hours. She recovered and continued acting after a short break (Wikipedia).

Current career status

As of 2025, Kim Yoo-jung remains active. She has taken career breaks to rest, but no major health incidents have been reported since 2012 (Wikipedia). She is set to star in the upcoming drama Dear Hyeri in 2025 (MyDramaList).

The implication: collapsed by exhaustion at 12, Kim Yoo-jung’s experience highlights the systemic issue of long working hours for child actors, even in top-rated productions.

Who is the Down syndrome actress in Korea?

Jung Eun-hye: actress and caricature artist

Jung Eun-hye is a South Korean actress with Down syndrome. She is not related to Kim Yoo-jung. The confusion arises because both are young actresses in the Korean entertainment industry. Jung Eun-hye gained public attention for her role in the 2022 drama Our Blues and also works as a caricature artist (Wikipedia).

• Jung Eun-hye was born with Down syndrome and has a visible intellectual disability (Wikipedia)
• She first appeared in advertising and later transitioned to acting (MyDramaList)
• Kim Yoo-jung has no connection to this actress — they share only a profession (YouTube – The Untold Story)

The clarity: two different people, same industry. Kim Yoo-jung has never publicly addressed this confusion, and no credible source links them.

How common is autism in Korea?

Autism prevalence in South Korea

South Korea has a reported autism prevalence of approximately 1 in 38 children (2.6%), which is among the highest globally. Data from the CDC (Autism and Developmental Disabilities Monitoring Network) and academic studies from the National Institutes of Health (NIH) database confirm these rates. However, autism and Down syndrome are distinct conditions, and the public often conflates the two in discussions about Kim Yoo-jung.

The takeaway: high autism prevalence in South Korea is a separate public health issue from the identity of any individual actress.

Her official Instagram handle is @you_r_love, with 15 million followers as of 2025 (Instagram). She follows 0 accounts, a notable detail that reinforces her personal boundary between public and private life.

Why this matters: her Instagram is a one-way communication channel — she shares updates but does not engage socially, which aligns with her reputation for privacy.
