“Idol-Like” Rapper-Actor Who Vanished Into Thin Air: His Mysterious Disappearance Still Leaves Fans Searching

Fans are once again asking the same haunting question: Where the heck is Jung Jae Won?

The rapper-actor, better known as ONE, was once considered one of the most promising rising stars in K-Entertainment. From his early days in 1PUNCH to his breakout on Show Me The Money Season 4 and later signing with YG Entertainment, his career trajectory seemed unstoppable. He even expanded into acting, with memorable roles in K-Dramas like Her Private Life and Arthdal Chronicles, and released his solo album, PRVT 01, further solidifying his unique artistic identity. His “idol-worthy” visuals definitely had him well in the spotlight, too.

But then… he just vanished.

While his activities began slowing around 2020, fans point to 2021 as the moment things took a more concerning turn. After briefly updating his profile photos, ONE once again withdrew from the public eye, eventually deactivating his social media accounts in 2022. Since then, there have been no official updates.

So, where is he now? The last widely cited sighting of the artist dates back to October 2022, when he was reportedly seen at a producer party at a club in Seoul. After that, the trail seemingly goes cold.

Despite the silence, small fragments of information have continued to surface. In 2024, producer Millennium played an unreleased track ONE had worked on years prior during an Instagram Live, hinting that the artist is still in contact with close collaborators. Around the same time, producer Ian Purp mentioned a possible 2024 comeback—but no release ever followed.

정제원이라는 미남래퍼 아는사람…(니알내아 맘편히 그사람맞음) 몇년전부터 실종돼서 아직도 노래듣고 기다리고있는데 머리카락 한올도 안보임 씨발, 오늘생일이라길래 생각나서 써봣어요 이분슬픈여자입니다 pic.twitter.com/j9FESVdSKh

Does anyone remember that handsome rapper Jung Jae Won…? (Yes, from that one song from Show Me The Money) He’s basically been missing for years, and I’m still listening to his music and waiting, but there’s not even the slightest sign of him. I heard it’s his birthday today, so he came to mind and I’m writing this. I’m just a sad girl.

Adding to the mystery, fans have pointed to a series of unexplained SoundCloud uploads believed by some to be connected to ONE. Several tracks appeared between 2023 and 2025, only to be deleted, reuploaded, and then disappear again. However, many remain skeptical, noting differences in musical style, vocal tone, and even the spelling of his name on the account.

With no confirmed statements and only scattered clues, speculation has continued to grow. Some believe ONE chose to step away from the industry entirely, while others hold onto hope that he may quietly return one day.

• When was the last time we heard from him??
• I’ve been keeping an eye on him since his 1PUNCH days, but at some point there were just no updates. I randomly thought of him a few weeks ago and searched everywhere, but there’s nothing at all…
• Yeah, at some point he just disappeared. Maybe he quit the entertainment industry altogether.
• Wait, same—I remember seeing a recent-ish update about him last year… but where is he now…??
• Not even exaggerating, he was seriously handsome.
• When I saw him on Show Me The Money, I remember thinking he was really good-looking.
• He was even a candidate to join WINNER.
• Seriously, since when did he disappear? I always thought he was so handsome.
• Oh!!! He’s the one who was in 1PUNCH with Samuel.
• I used to like him so much… Where did he go…?
• Could he have gone to the military?
