What happened to Lee Sung‑kyung and Nam Joo‑Hyuk?

The relationship between Lee Sung‑kyung and Nam Joo‑Hyuk remains one of the most searched questions about her. Here is what is confirmed.

How did their relationship start?

• They met on the set of Weightlifting Fairy Kim Bok‑joo (2016–2017), where they played a couple. Their agencies confirmed the relationship in 2017 (Wikipedia).

• Neither side has given a detailed public explanation since.

Are they still on good terms?

• Both remain private about their current relationship status. No public friction has been reported.
• They have not been seen together publicly after the split, but no animosity is known.

The pattern: on‑screen chemistry turned into a real relationship that lasted about a year, then faded under the weight of careers. Fans still wonder, but the public record stops in 2018.

Are Lee Sung‑kyung and Suga friends?

Yes. Lee Sung‑kyung and BTS’s Suga maintain a friendship that predates both of their big‑name fame.

How did they become friends?

• They attended the same high school – Apgujeong High School – though not the same year (Wikipedia).
• Suga has mentioned her on variety shows as a supportive friend from his trainee days.

Have they collaborated musically?

• No musical collaboration has been publicly released. Lee Sung‑kyung has released solo OSTs and a cover single with Eddy Kim, but not with Suga.

What have they said about each other?

• Suga once said on a broadcast that Lee Sung‑kyung was one of the few celebrity friends he could rely on (Wikipedia).
• She has never publicly elaborated on the friendship beyond acknowledging it in interviews.

The implication: these are two artists from the same neighborhood who kept in touch while ascending different industries. The friendship is real but kept deliberately low‑key.

What is the age gap between Lee Dong‑Wook and Lee Sung‑kyung?

Both actors co‑starred in the 2017 drama The Bride of Habaek. Their age difference is often brought up by viewers.

How old is Lee Sung‑kyung?

What is the exact age difference?

• The gap is approximately 8 years and 9 months.
• In Korean age reckoning, the gap is 9 years.
• The drama intentionally downplayed the age difference in its storyline.

Why this matters: in K‑drama casting, age gaps of this size are sometimes controversial, but the two actors’ professional chemistry muted most criticism.

Is Lee Sung‑kyung married?

Has she ever been engaged?

What is her current relationship status?

Are there any marriage rumors?

• No substantive marriage rumors exist. Speculation online is often tied to her friendships, not relationships.

The trade‑off: Lee Sung‑kyung’s private life is heavily guarded. Fans will likely only learn of a marriage if she chooses to announce it publicly.

How tall is Lee Sung‑kyung?

• Her stature often requires camera and casting adjustments, especially when acting opposite shorter male leads.

The catch: her height was an asset as a model, but in K‑drama it sometimes limits her pairing options. Still, it has become part of her signature image.
