Wanna One Go: Back to Base Episode 1 is the starting point fans had been waiting for: a return to Wanna One’s reality-show world after seven years. Released first on Mnet Plus at 6 p.m. on April 28, 2026, and broadcast on Mnet at 8 p.m. the same day, the premiere focuses on the April 6 opening ceremony in Sangam-dong and the members’ entrance into their new shared space, Wannabase.1
For anyone following Wanna One Back to Base, Episode 1 matters because it does not simply restart an old format. It frames the reunion around a place, a memory, and a group dynamic that has had years to mature. The official teaser described the members gathering again at a new base, laughing, making memories, and becoming a stronger “we,” which fits the emotional direction of the first episode.2
Wanna One Go: Back to Base Episode 1 Begins at Sangam

The premiere reaches back to the opening ceremony held on April 6, 2026, at DMC Culture Park in Sangam-dong, Mapo-gu, Seoul. That setting carries extra meaning because the source material describes it as the place connected to the members’ first meeting nine years earlier.3 Episode 1 uses that ceremony as one of its main anchors, showing behind-the-scenes moments from the event before moving the story toward the members’ new living space.1
Nine members attended the ceremony in person: Park Ji Hoon, Lee Dae Hwi, Kim Jae Hwan, Ong Seong Wu, Park Woo Jin, Yoon Ji Sung, Hwang Min Hyun, Bae Jin Young, and Ha Sung Woon. Yoon Ji Sung and Lee Dae Hwi also served as MCs. Kang Daniel and Lai Kuanlin were not present in person, but the members referred to them through playful situational acting using standees.3
The ceremony also gave fans the kind of short, emotional lines that make a reunion feel real. Hwang Min Hyun said, “It has been a long time since I called the name Wannable, and it feels moving to be together again.” Lee Dae Hwi summed up the mood more simply: “Wanna One is just beginning.”3
What Episode 1 Shows Inside Wannabase
After the ceremony material, Episode 1 follows the members as they enter Wannabase, the new living space created for the show. The main poster, released by Mnet Plus on April 14, presented the concept visually as a house-like space with rooms for all 11 members, each reflecting individual tastes and character.4
That house concept is useful because it gives the show a clear emotional structure. Rather than only presenting a reunion as a one-time event, Back to Base places the members in a shared setting where old habits, new personalities, and small everyday exchanges can surface naturally. Based on the available episode details, the premiere introduces that space as a central part of the series rather than just a backdrop.
The tone also appears lighter than the long gap might suggest. In an Episode 1 preview moment, Park Woo Jin jokes, “I think I’m past the age of playing with things like that,” referring to toys.1 It is a small line, but it captures one of the most interesting tensions of this comeback: these are the same members fans remember, but they are returning after years of change.

Why the First Episode Had Buzz Before It Aired
The return did not arrive without buildup. A B-Side video released on April 21 showed the members’ first gathering after seven years, and Sports Donga reported that related keywords rose on X real-time trends after the video was released.5 The same report noted that the video included Kang Daniel entering for enlistment, Ha Sung Woon heading to Beijing, and a meeting between director Jang Hang Jun and Park Ji Hoon.5
The full member lineup tied to the new reality program includes Kang Daniel, Park Ji Hoon, Lee Dae Hwi, Kim Jae Hwan, Ong Seong Wu, Park Woo Jin, Lai Kuanlin, Yoon Ji Sung, Hwang Min Hyun, Bae Jin Young, and Ha Sung Woon.6 That complete lineup is part of why the phrase “seven-year reality return” carries weight here. The show is not being framed as a small side project, but as a reunion built around the identity of Wanna One as 11 members.
The official teaser page also reinforces that the series is not only about nostalgia. Its description points toward the members gathering at a new base and making fresh memories together.2 That makes Episode 1 feel like a bridge: it acknowledges the emotional pull of Sangam and Wannable, then moves the members into a new setting where the rest of the series can unfold.
