He continued, "While I was talking to him, I suddenly wondered how many messages we had sent each other in our group chat while he was offline. So, I asked him that."
He laughed and added, "Hyung Sik told me that about 4,300 messages accumulated in the group chat over his 5-week military training. I was like, 'Wow.'"
Then, Park Seo Jun said, "I told him this yesterday as well, but I really hope he takes good care of himself there. Most of all, no injuries. Nobody would want that for sure."
