'International bnt' released Sungjong's solo pictorial and interview. 

Following the photoshoot, Sungjong sat down for an interview, where he talked about his acting gig, radio, INFINITE, and more. 

Sungjong shared the secret to INFINITE's long-lasting bond, stating, "I think the secret to our bond is honesty and consideration. We tell each other right away if there's something we're upset about and we tend to well accept them."

He also talked about military enlistment. Sungjong said, "I'm not sure about my military enlistment plans yet but I'm considering many options. We once thought about enlisting all at once but that fell apart due to various situations. I'm thinking of various directions since I do have some time."
