'CÓ KHI' takes Nhà Lục Lạc into a different shade at Công diễn 5 of Anh Trai Vượt Ngàn Chông Gai 2026. After the high-energy 'Chuyện Chàng Cô Đơn', Thỏ (Da LAB), K.O, Duy Khánh, Thanh Duy, Will and Cheng chose to restrain movement and put the singing and emotion at the center. Behind that seemingly simple stage is no small puzzle: how can six distinct personalities each leave a mark while telling one story. Watching says it best, so DETOON puts the video right here.

From 'Chuyện Chàng Cô Đơn' to an almost opposite stage

At Công diễn 5, Nhà Lục Lạc brought two numbers with quite different tones. 'Chuyện Chàng Cô Đơn' came first with Thanh Duy, Thỏ (Da LAB), Will, K.O, Cheng and Duy Khánh; the official release runs 4 minutes 16 seconds.

With 'CÓ KHI', the group pivots. Instead of leaning on performance energy, they reduce movement so viewers focus on the vocals and emotion of the six members. VTV described it as a number posing the puzzle of blending six different vocal colors within one performance. The shift makes 'CÓ KHI' a clear counterweight to the earlier stage: one toward performance energy, the other deliberately slowing down to let singing lead the story.

With six on stage, the challenge isn't simply splitting singing time evenly. Each needs a part clear enough for the audience to recognize their color, yet those parts must link into one unified number. That became a notable part of how Nhà Lục Lạc built 'CÓ KHI'.

Five of six members wrote their own parts

Per Thanh Duy, as reported by the media, five of the six members wrote their own additional parts. This forced the group to adjust repeatedly so the X-parts wouldn't become disjointed, while keeping the song's shared emotional thread.

It's an interesting detail because it shows the difficulty of a multi-member number doesn't necessarily lie in how complex the staging is. On the contrary, when each person wants to bring their own personality into the song, the question becomes: how do six personal stories still sound like one shared story? So the members didn't just stand side by side singing pre-assigned parts — they took part in shaping how the number is delivered.

When 'less movement' is a deliberate choice

A stage with less movement doesn't mean less preparation. By cutting big performance elements, viewers get more room to notice: how each member handles a line, the transitions between voices, how the X-parts fit the song, and the emotional thread from start to end. VTV and Vietnam.vn both note Nhà Lục Lạc deliberately chose a restrained style to focus on singing and emotion.

It's a choice with its own risk. The less there is on stage to distract, the more the vocals and the members' connection become noticeable.

'CÓ KHI' sits in the Chốt Hạ round of Công diễn 5

'CÓ KHI' appeared in episode 13, in the Chốt Hạ (closing) part of Công diễn 5 — the stretch right before the finale of Anh Trai Vượt Ngàn Chông Gai 2026. After Công diễn 5, Will left the show, along with Thuận Nguyễn of Nhà Thăng Hoa. So 'CÓ KHI' also became one of Will's last stages this season.

The song has also been officially released

Besides the YouTube performance, 'CÓ KHI' is on the album CÔNG DIỄN 5 (Anh Trai Vượt Ngàn Chông Gai 2026) released September 26, 2026. Apple Music lists the audio at about 3 minutes 56 seconds, credited to Anh Trai Vượt Ngàn Chông Gai, Thanh Duy, Thỏ (Da LAB), Will, K.O, Cheng and Duy Khánh.

That also explains why you may see different durations between the audio and the performance video: the YouTube video is indexed at about 4 minutes 35 seconds, while the official audio release is shorter.

'CÓ KHI' shows notable search signals

As of the check on October 1, 2026, 'CÓ KHI' stood at #2 on the Vietnam iTunes chart tracked by Soundcharts. The performance video was also noted at #5 on YouTube Trending Vietnam on September 29, with over 230,000 views at the time the tracker recorded it.

These two data points don't automatically prove lasting heat, but they show 'CÓ KHI' is drawing significant attention right after Công diễn 5 aired.

You don't need a lot happening to make a memorable stage

What stands out about 'CÓ KHI' ultimately isn't how many props or how much movement the stage has. Nhà Lục Lạc tries an almost opposite direction: reduce what happens around so listeners pay more attention to the six people singing.

And when five members each write their own parts, the performance minimalism comes with a fairly complex process behind it. One person must leave a mark. Six people must leave six marks. Yet when the song ends, listeners still need to feel: they just heard one number — not six numbers stitched together. That's perhaps the most interesting puzzle behind 'CÓ KHI'.
