On Thursday, March 14, k-pop fans were abuzz with excitement after Park Ji Hoon has dropped a teaser photo for his forthcoming mini-album, O'Clock. The said photo sees him sporting a burgundy hair, which gives off a dark and sexy vibe while maintaining a solemn expression.

The first concept photo gives fans an idea of what to expect from the forthcoming album O'Clock, which reportedly revolves around the theme of love - particularly, the joy, innocence, and passion of romance.

The second concept photo will be released on March 15, while the mini-album's official track list will be revealed on the 18th. As for the music video teaser and album, it is expected to hit the internet on the 20th and 22nd, respectively. The full mini-album, on the other hand, is set to drop on the 26th at 6:00 p.m. KST.

For those who are unfamiliar, Park Ji Hoon first debuted as a child actor for musicals such as 2007-2009's Peter Pan, 2010's The Harmonium in My Memory and 2010-2011's Radio Star. He also appeared on several television series, including Jumong (2006-2007), The King and I (2007-2008), Kimchi Cheese Smile (2007-2008), and Iljimae (2008).

He, then, gained widespread fame after ending up as a runner-up contestant in Mnet's Produce 101 Season 2 -  which made him a member of the project boy group, Wanna One, under YMC Entertainment.

Park Ji Hoon is said to be the fourth member to embark on a solo career following Lai Kuan Lin, Ha Sung Woon and Yoon Ji Sung. While he's feeling a bit nervous about the whole thing, he also hopes to surprise the public with his music as a solo artist.

"As a singer, I'd like to be able to pull off any genre on stage," Park Ji Hoon said in a sit-down interview with Singles Magazine, as quoted by Soompi. "I'm planning to show many different sides of myself and shatter the preconceived image that the general public has had of Park Ji Hoon up until now," he added.
