Forestella's Ko Woo Rim is enlisting for his mandatory military service.

On September 26, Ko Woo Rim wrote a letter to fans about his upcoming military enlistment on November 20 KST. The singer expressed, "As of November 20, 2023, I'll receive basic military training and serve in the military band of the Ministry of National Defense... Fortunately, I will be able to finish the Forestella Festival and the rest of our concerts and events before enlisting, so I'm very thankful for this."

He added, "I hope you'll take this news with happy and light hearts as I'll return in good health after completing my national defense duties."
