In a recent development, INFINITE's Sungjong has informed his agency, SPK Entertainment, about his decision to terminate his exclusive contract. Reports suggest that this decision stems from issues related to non-payment of an exclusive deposit, settlement fees, and a deteriorating trust relationship. Sungjong's representatives have shared that they intend to release a formal statement about his position soon.

Sungjong, who made his debut as a member of INFINITE in 2010, gained immense popularity with chart-topping songs. He also contributed to INFINITE's 7th mini album, 'Begin,' which was released in July.
