Park Se Jun, formerly known professionally as KIDZ and currently known as Park Seo An, is a South Korean singer, dancer, actor and former member of SPEED (스피드). He graduated from Hanlim Entertainment Arts High School, and before debuting, he lived in Vancouver, Canada, for nearly 3 years.

MBK Entertainment (MBK엔터테인먼트, formerly known as Core Contents Media) debuted their idol group, COED SCHOOL, in September 2010. The agency later decided to create two separate groups, one for the boys and another for the girls. The newly formed boy group SPEED released a pre-debut single album titled "Hommage to Lovey-Dovey" in January 2012 as a tribute to T-ARA's "Lovey-Dovey". As part of a restructuring, he was added as a new member one day later.

He made his debut in January 2013 as SPEED's rapper, vocalist and visual with their digital single "Speed of Light." He also promoted as a one-man sub-unit under the stage name KIDZ.

In November 2015, MBK announced the group's disbandment. The following year, he announced he would become an actor after having had two minor roles in a pair of 2013 dramas.

He enlisted for his mandatory military service in 2018, and after being discharged, he changed his stage name to Park Seo An but has no acting credits at all.

He currently runs a music video production business.
