On March 27, Choi Woo Sik posted two pictures of his recent get-together with the 'Wooga Squad' members for his 33rd birthday celebration on March 26.

Along with the adorable photos of the squad members smiling brightly and showing their natural charms, Choi Woo Sik wrote, “I had a great birthday!” expressing gratitude to his close friends.

The 'Wooga Squad' is a popular clique of celebrity friends, comprising BTS's V (Kim Taehyung), Park Seo Joon, Park Hyung Sik, Peakboy, and Choi Woo Sik. The term “Wooga” is short for the Korean phrase, “Woori-ga gajok-inga?” which means, “Are we family?” and represents their unbreakable friendship.

In 2022, the 'Wooga Squad' appeared together on "In the SOOP: Friendcation," a 4-episode travel reality series that exhibited their strong bond and camaraderie. 

Currently, three members of the squad, namely Choi Woo Shik, Park Seo Joon, and BTS's V, are featuring on "Jinny's Kitchen," Prime Video's first Korean variety show where they showcase their cooking skills and indulge in fun activities set in Bacalar, Mexico.
