WEi Drops 'Save' as Group Enters Solo Era After 2,000 Days Together

WEi (위아이) released digital single "Save" on March 27, 2026, their 2000th day since debuting with Oui Entertainment on October 5, 2020, according to the label's official release. The milestone track arrived two days after Oui confirmed that all six members, Jang Dae-hyeon, Kim Dong-han, Yoo Yong-ha, Kim Yo-han, Kang Seok-hwa, and Kim Jun-seo, will pivot to solo activities while continuing to promote under the WEi name. The announcement posted by Oui Entertainment on March 25, 2026, marks the most significant restructuring in the group's five-year run. "Save" was co-written and composed by leader Jang Dae-hyeon alongside RYVNG and Maynine of production team Stupid Squad and Oh Hyung-seok. The R&B single functions as both a tribute to the group's fandom, the RUi, and an implicit promise that this transition is a beginning, not an ending.

The Announcement: A Pivot, Not a Break

Oui Entertainment posted the statement on March 25, 2026, via the group's official Daum Cafe community page. The label described the shift as all members concentrating on individual activities in the near future, while the WEi name remains active. The phrasing mirrors a pattern that has become increasingly familiar in K-pop, where groups approaching military enlistment windows or individual career peaks need structural flexibility without the reputational cost of an official hiatus announcement. WEi's fandom already knew the situation was coming. In November 2025, Oui confirmed through Soompi that Jang Dae-hyeon would limit his group activity starting January 2026 as he prepared for mandatory military service, and that Kim Yo-han would step back after December 8 to focus on an acting project. The March 25 announcement formalizes what the RUi fanbase had been tracking for months.

Save: A Letter to 2,000 Days

The single's imagery is doing a lot of the emotional work here. The official artwork for "Save" is a sealed letter, stamped with WEi's wax logo in deep burgundy, sitting on cream parchment paper. It is overtly referential: this is a message from the group to their fans, delivered on the precise day marking five and a half years together. Leader Jang Dae-hyeon co-wrote the song with RYVNG and Maynine of production team Stupid Squad alongside Oh Hyung-seok, per the song's official production credits published on Korean streaming platforms on March 27, 2026. The genre leans R&B, a departure from the group's more kinetic pop sound on recent EPs like Wonderland. The title itself carries a double meaning: "Save" as in preserve, hold onto, and also "Save" as in what the RUi's sustained support has meant across 2,000 days.

A Group Built from Survival Shows

WEi is unlike most K-pop groups in that every single member arrived through a reality competition show. Jang Dae-hyeon and Kim Dong-han competed on Mnet's Produce 101 Season 2 in 2017, with Dong-han finishing 29th and later debuting in JBJ before that group disbanded. Yoo Yong-ha and Kim Jun-seo both placed in Under Nineteen and debuted together in 1the9 in April 2019. Kim Yo-han made the biggest splash, winning Produce X 101 according to Mnet's official broadcast results and debuting as center of X1 on August 27, 2019, only for the group to disband four months later when Mnet's vote manipulation investigation brought the entire Produce franchise down. Kang Seok-hwa nearly made YG Entertainment's Treasure lineup through the YG Treasure Box competition before signing with Oui under Kim Yo-han's recommendation. When Oui assembled WEi in May 2020, they were collecting five years of survival show near-misses into something built to last.

The Pieces Had Been Moving

The announcement didn't come from nowhere. Kim Jun-seo had already departed WEi in 2025, stepping away temporarily to compete on survival show Boys II Planet before debuting in ALPHA DRIVE ONE in November 2025, making his exit from WEi effectively permanent. That left the group at five active members heading into their 8th mini album Wonderland, which dropped October 29, 2025 per Oui Entertainment's official release schedule. Kim Yo-han has been splitting his time between WEi activities and an increasingly high-profile acting career since at least 2022. His documented absences from the group's 2023 world tour and multiple Japanese releases pointed toward a parallel solo trajectory well before any announcement. Now, with Wonderland in the rearview and Jang Dae-hyeon's enlistment on the horizon, Oui has simply put a name on what the RUi already knew.

What the Solo Era Actually Means

The March 25 statement doesn't outline specific timelines for individual releases. What the solo pivot likely means in practice: expect each member to move at their own pace across music, acting, and variety, while WEi group activities continue selectively for pre-coordinated events. On X (formerly Twitter), the tags #세이브 and #WEi_SAVE trended in South Korea on March 27, 2026, according to X's trending data for the region, signaling the RUi's continued engagement. Whether WEi returns for a full group comeback after Jang Dae-hyeon completes his mandatory military service (typically 18 to 21 months) depends on how the solo era plays out for each member. Five years from Boys II Planet dropouts, Produce survivors, and a disbanded X1 center, WEi was always a group built on the premise that second acts are possible. The solo era is just the latest proof.
