Pentagon's Yeo One has officially started his mandatory military service.

On May 28, Yeo One revealed to fans he'd enlisted in the military today. He shared the below photos of himself with a buzz cut on Instagram along with the message, "Hello, this is Pentagon's Yeo One, Yeo Changgu. In 1 year and 6 months, confidently without being ashamed of myself, I'll come back as a cooler man in front of Universe. Don't worry, and I hope you stay healthy and happy. Let's meet again at the end of next year with a smile on our faces. I'll do my best to greet Universe. Thank you, and I love you always. I'll be back."

Yeo One also used Pentagon's song for their fans "With Universe" as the post's BGM. His fellow Pentagon member Jinho commented, "My baby, come back safely," while Kino expressed, "Giant potato." Hongseok and Hui are said to have personally sent him off at his training base.

Stay tuned for updates on Yeo One and Pentagon.
