Park Hyun Ho, formerly known as Seo Goong, is a South Korean singer, dancer and former member of TOPP DOGG (탑독). He graduated from Pungdeok High School and enrolled in the Broadcasting Entertainment program at Yewon Arts University but was on a leave-of-absence before obtaining a bachelor's degree in the same program from Global Cyber University.
He debuted in 2013, using the stage name Seo Goong, as the group's main vocalist with their first EP, "Dogg's Out." The group was not very successful, and the style did not fit all the members. So, he decided to leave the group in early 2015 and was originally moved to a sub-unit called UnderDogg, but it quickly disbanded, and he left the company.
After performing as a musical actor, he signed with Dream Tea Entertainment and made his solo debut with the song "Try", using the stage name I’M. He enlisted for his mandatory military service on March 12, 2018, and was discharged on November 10, 2019.
