ONEW & YUJU Are About to Give K-Pop Fans a Vocal Moment: Everything to Know About “Mind Games”
SHINee's ONEW and GFRIEND's YUJU are joining forces—and K-pop fans already have plenty of reasons to be excited.
Some collaborations make you curious.
Others make you immediately reach for your headphones.
ONEW and YUJU's “Mind Games” is looking like the second kind.
The SHINee vocalist and GFRIEND singer are teaming up for a duet that arrives on September 29 at 6 p.m. KST, serving as the first title track from ONEW's upcoming single album Chakgak (착각).
And fans have already received a taste of what's coming.
On September 27, ONEW released a teaser video featuring a highlight of “Mind Games,” giving listeners their first glimpse of the collaboration ahead of its full release.
With two distinctive vocalists at the center of the track, this is one September K-pop release that's worth putting on your radar.
🎤 ONEW × YUJU: Why This Collaboration Has Fans Talking
Let's start with the obvious:
These are two vocalists who know exactly how to make a melody memorable.
ONEW has built a reputation around his distinctive, warm vocal tone as a member of SHINee while continuing to develop his identity as a solo artist.
YUJU, meanwhile, is known for her powerful yet expressive singing, first gaining widespread recognition as a member of GFRIEND before establishing her own solo career.
Put those voices together, and you immediately get a very intriguing contrast.
The teaser released ahead of “Mind Games” reportedly showcases portions of the two singers' voices blending, with ONEW's agency Griffin Entertainment describing the song as one that highlights delicate expression and vocal synergy.
And that is exactly the kind of collaboration that can make fans listen once...
Then immediately press replay.
🎧 “Mind Games” Is Only the Beginning
Here's where ONEW's new project gets particularly interesting.
“Mind Games” isn't simply a standalone collaboration.
It is the first of three title tracks connected to ONEW's upcoming single album Chakgak.
The Korean word "chakgak" (착각) translates to "mistaken impression", "illusion", or "disillusion", where someone misunderstands or misinterprets the situation. ONEW plays on this theme by exploring the emotional weight of illusions, false expectations, and misread signs.
Rather than dropping everything at once, ONEW is rolling out the project's title tracks in stages.
Here's the schedule:
📅 September 29 — “Mind Games”
The first title track arrives at 6 p.m. KST, with YUJU joining ONEW for the duet.
📅 October 7 — Second Title Track
ONEW will follow “Mind Games” with a second title track on October 7.
📅 October 20 — Third Title Track + Full Chakgak Release
The third title track and the complete single album Chakgak are scheduled for release on October 20 at 6 p.m. KST.
That means ONEW isn't giving fans just one comeback moment.
He's essentially creating a three-stage rollout.
And “Mind Games” is the opening chapter.
🧩 What Does “Mind Games” Sound Like?
Based on the preview released September 27, fans have already been able to hear a short highlight of the song.
The available preview points toward a track centered on the vocal interplay between ONEW and YUJU, rather than simply using one singer as a background feature for the other.
That's important because this is being presented as a genuine duet.
The two voices get to exist together.
Griffin Entertainment has specifically highlighted the song's delicate expression and the synergy between the singers.
So while fans will have to wait for the complete track to fully judge its musical direction, the teaser has already established the biggest selling point:
ONEW + YUJU's voices.
And honestly, that might be enough to have half of K-pop Twitter reaching for the replay button.
💙 SHINee WORLD × BUDDY: A Fandom Crossover
There's another reason this collaboration feels particularly fun.
ONEW brings SHINee WORLD into the conversation.
YUJU brings BUDDY.
And suddenly, two fandoms have a shared song to obsess over.
That means “Mind Games” isn't just another new release appearing in an already packed K-pop calendar.
It's also a chance for longtime fans of both artists to see two established vocalists step into the same musical space.
For fans who have followed ONEW's solo journey and YUJU's evolution beyond GFRIEND, the collaboration carries an additional layer of anticipation.
It's not simply:
“What will this song sound like?”
It's:
“What happens when THESE two voices meet?”
🌟 ONEW Is Taking a Different Approach to His Next Solo Era
Chakgak also marks another step in ONEW's solo career.
The project arrives approximately seven months after his fifth mini album TOUGH LOVE. Griffin Entertainment says ONEW previously demonstrated his musical abilities not only as an artist but also as a producer through that project.
Now he's taking another ambitious approach with the three-title-track format.
Instead of asking fans to absorb an entire project in one day, the rollout gives each title track its own moment.
That could make the “Chakgak" era feel less like a single comeback day and more like a musical story unfolding over several weeks.
And “Mind Games” gets to set the tone.
👀 What Fans Should Watch For
Once the full release arrives, there are a few things worth paying attention to.
1. The Vocal Chemistry
This is obviously number one.
How do ONEW's warm vocal color and YUJU's expressive delivery interact when they share the same song?
That's the entire reason this collaboration is so intriguing.
2. The Chorus
The teaser gives only a small taste of the song.
The full chorus—and especially how the two singers trade or blend lines—could become one of the most replayed sections.
3. The Music Video
Fans will also want to see whether the “Mind Games” visual concept plays directly into the title.
Is the song romantic? Psychological? Dreamlike? Conceptual?
The complete MV should provide a much clearer picture.
4. The Lyrics
With a title like “Mind Games,” fans are inevitably going to examine the lyrics for clues about the emotional story behind the song.
And once translations start appearing, expect the analysis to begin.
5. How It Connects to Chakgak
Because “Mind Games” is only the first of three title tracks, fans may also start looking for connections between the songs.
Could recurring imagery, emotions, or themes appear throughout the rollout?
That's something we'll only know as the remaining releases arrive.
