On October 28 episode of SBS' variety show 'Master in the House', Yook Sungjae wrote a letter to Seo Eunkwang who began serving his national mandatory duty in the military back in August.
The letter started off very warmly, "I hope to deliver some energy to Eunkwang hyung who is having a rough day every day with all that training in the military."

Then, the letter started showing a little bit of a twist, "A few days ago, I saw some pictures of you in the army. I was relieved to see you smiling, but at the same time, I felt upset as you seemed to have forgotten about me and are doing well without me."

Yook Sungjae playfully commented, "Please play Lee Moonsae's song 'Past Love' with this letter."

He continued, "But Eunkwang hyung looked too happy there. He happened to be placed in the same dorm as Yoon Du Jun from another boy group Highlight as well. They seemed to have adapted well to the military life."

Meanwhile, BTOB released a new song 'Friend' on October 23, which the group had recorded before Seo Eunkwang enlisted.
