Wanna One's Ong Seong Wu has shared a heartwarming story about his friendship with fellow members Hwang Min Hyun and Ha Sung Woon, revealing that he personally arranged for them to attend military reserve training together because he did not want to be alone again.

On November 5, Ong Seong Wu shared photos of himself with Hwang Min Hyun and Ha Sung Woon through a fan communication platform, showing the three former Wanna One groupmates attending reserve training together.

Alongside the photos, Ong Seong Wu explained that his previous experience attending the training alone had been surprisingly lonely.

*"When I tried doing it alone last year, I felt so lonely,"* he admitted.

Rather than going through the same experience again, he decided to find a way for his friends to join him.

*"I wondered if there was a way we could do it together. When I found out there was, I kept checking the registration dates. As soon as an available location appeared, I gathered everyone and signed us up,"* he explained.

His efforts paid off, allowing the three singers to complete their reserve training together.

Ong Seong Wu admitted that having familiar faces around made the experience much more comfortable.

*"It was so much better having them with me!"* he shared.

He also explained why he had wanted company in the first place.

*"Normally, you go there alone for eight hours a day over four days. You eat alone and walk around alone,"* he said.

His story offered a glimpse into the close friendship that Ong Seong Wu, Hwang Min Hyun, and Ha Sung Woon have maintained since their Wanna One days.

Wanna One was formed through Mnet's *Produce 101 Season 2* in 2017 and officially concluded its original group activities when its contract expired on December 31, 2018.

The members later reunited for *WANNA ONE GO: Back to Base*, bringing back memories of their time together.

While their careers have taken different paths, Ong Seong Wu's latest update shows that their friendship continues beyond the stage.

What could have been another lonely military training experience became an opportunity for three Wanna One members to spend time together, thanks to Ong Seong Wu's determination to bring his friends along.
