Singer and broadcaster Kim Song expressed her deep sorrow over the passing of Seo Hee Won (Barbie Hsu), the wife of Koo Jun Yup.

On the 4th, Kim Song shared her heartfelt condolences on social media, writing, "I was shocked when I heard the unbelievable news yesterday."

She reflected on her husband's reaction, saying, "My husband told me to stay in bed because he was leaving for work. He can't express his emotions well, but he probably cried alone." Kim Song is married to Kang Won Rae, who was a member of the group Clon alongside Koo Jun Yup.

Kim Song also shared how Koo Jun Yup, usually quick to reply to her messages, was silent until late at night. "All I could do was pray. Even in such a painful moment, he still said thank you and asked me to pray for Hee Won to rest in peace," she wrote. She continued, "When Hee Won was struggling, their reunion must have been such a source of support and comfort, even if it was for a short time. I was grateful to witness it… I cried during the day when no one was around."

Kim Song also condemned malicious comments online, stating, "Some people have been blaming Kang Won Rae and Koo Jun Yup’s wife for their fate. I have nothing to say… I know there will be hate comments under this post too."

She then addressed Koo Jun Yup directly, writing, "Gugu oppa, you may not believe it now, but don’t hold back your tears. Cry as much as you need to. Don’t just say you’re okay—let yourself grieve so that you won’t have regrets." She concluded her post with, "Unnie~ I miss you~ I pray that Hee Won, who used to call me that, can now rest in peace."

Seo Hee Won (Barbie Hsu) was previously married to Chinese businessman Wang Xiaofei in 2011, and they had a son and a daughter together before divorcing in 2021. After learning of her divorce, Koo Jun Yup reached out to her, rekindling their past romance. The two married in 2022.

However, Seo Hee Won passed away on February 2nd in Japan due to acute pneumonia following the flu. She was 48 years old.

Koo Jun Yeop and Seo Hee Won originally dated in 1998 but separated after about a year. Their reunion after 20 years and eventual marriage was widely regarded as a heartwarming love story.

Here is Full Translation of Kim Song's SNS Post

This morning, I hurriedly woke up Seon-i, got her ready for school, packed my husband's lunch, and lay back down. As he was leaving for work, my husband told me to stay in bed and not get up.

Yesterday, I was completely devastated after hearing the unbelievable news. There was nothing we could do, so we just spent the time feeling helpless.

My husband, who usually says nothing, took out some alcohol—something he hadn’t been drinking recently because of his cold—and drank alone in his room. He can't express his emotions well, but I think he must have cried alone.

Oppa, who always replied to my KakaoTalk messages right away, didn’t respond for a long time. It wasn’t until late at night that I finally heard from him. "I’m sorry I couldn’t do anything to help… All I can do is pray…" And even in his pain, he still said "thank you." He asked me to pray for Hee Won to rest in peace. Until the very end, it was always "Hee Won, Hee Won..."

When Hee Won was struggling, they reunited like something out of a movie. The time they spent together, though short, must have been such a source of strength and comfort for her… Even as someone watching from the side, I was grateful for that. I broke down and cried during the day when no one was around.

People leave words of comfort, but there are also those who post hateful comments, blaming fate for Kang Won Rae’s disability and now for Goo Jun Yup’s wife’s passing. Truly… I have no words. I know there will be hate comments on this post too.

From the moment they first met, we were there. We quietly watched from the sidelines, supporting each other without needing to say a word. Gugu oppa, right now, you may not believe it, but don’t hold back—cry as much as you need to. Don’t force yourself to be okay. Cry, so you won’t have any regrets. Let yourself put a meaningful final period on your love story without holding back.

I pray that Hee Won, who used to call me "Unnie, unnie~ I miss you~" in her adorable voice, can now rest peacefully. Please offer comfort and support so that they can heal from this pain quickly.

P.S. I’ll be taking a short break from Songsong Market for a few days.

Please join in prayer with one heart.
