The agency revealed the news on July 31, by stating, "He has renewed his contract which had nearly a year left before it ended."
The CEO stated, "Even though there's nearly a year left before his contract ends, in order to build the long-run plan towards his future activities, Park Seo Joon was the first to express intention to renew his contract. We will continue to trust and have steady communication with Park Seo Joon for his lively promotions, and wholeheartedly support him so he can grow."
Park Seo Joon has been with Key East since his debut in 2011 and he's shot up in popularity since then. It looks like this agency is a good fit for him and we're looking forward to seeing him in new drama 'She Was Pretty' soon!
