Overview
- Vernon began his mandatory military service by entering a training center to start basic training on Thursday before moving into a public service worker assignment.
- Hours after entering the training center he released a digital single titled "I'll Be Back," which he wrote and helped compose.
- "I'll Be Back" is an electronic pop track meant as a parting message to fans and was released at 6 p.m. on the day of his enlistment.
- Pledis Entertainment formally announced the enlistment in advance and asked fans not to visit the training center or his future workplace to protect privacy and safety.
- Vernon’s service comes as SEVENTEEN manages staggered military duties across members while continuing selected group and solo activities and fans should expect rotating lineups until members return.
