In 2017, the second season of Produce 101 aired, showing the selection process for the boy group WANNA ONE.

Like the previous season’s winners, I.O.I., WANNA ONE saw significant popularity before the group’s disbandment in 2019. Afterward, the members began other activities, with some debuting in new groups or as solo artists.
Earlier this year, it was announced that the members would reunite for a special program titled Wanna One Go: Back to Base.

However, only nine out of the original eleven members were present for filming, with the show’s number one pick, Kang Daniel, currently serving out his mandatory enlistment.
The other missing member, Lai Kuanlin, debuted in a duo with PENTAGON‘s Wooseok, Wooseok x Kuanlin, before he requested the termination of his contract with Cube Entertainment. After this, he focused his career in China, where he worked as an actor until 2024, when he announced his retirement to “switch careers” and now focuses on directing off-camera.

In the episode released on April 21, it was hinted that member Sungwoon had traveled to China to meet with Kuanlin, a claim confirmed in the latest episode. Sungwoon is shown walking through the airport after his flight, where he is met by Kuanlin, with captions confirming that the reunion will be shown in detail in the following episode.
