Park Seo Ham is a South Korean rapper, dancer, actor and former member of KNK. He graduated from Gunseo High School. Before debuting, he spent several years as a trainee at Big Hit Entertainment alongside members of BTS. He then moved to JYP Entertainment, placing 2nd at the company’s 10th Open Audition and training with GOT7 members. After arriving at YNB Entertainment, he appeared in music videos of their label mate, Bestie, and performed as a backup dancer for the girl group.
He made his debut in 2016 as the group's main rapper, vocalist, visual and face of the group with a debut showcase and the release of their 1st single, "Knock". In 2017, all group members at the time entered the singing survival competition "MIX NINE", and he ranked 32nd overall. A year later, it was announced that KNK and YNB Entertainment ended their contract and that the members were planning on continuing the group with another agency.
In early 2019, they signed with 220 Entertainment and had several tours in the US and in Europe. In 2020, they released their 3rd EP, "KNK Airline", and afterwards, lineup changes and mandatory military enlistments have caused the group to nearly stop promoting for the time being.
In late 2021, it was announced that he was leaving KNK and YNB Entertainment after his contract expired, and he decided not to renew it. He debuted as an actor with a minor role in "20th Century Boy and Girl" in 2017 and had the lead role in the hugely successful BL web drama "Semantic Error" in 2022.
On March 7, 2022, he signed an exclusive contract with NPIO Entertainment as an actor, and 3 days later, he enlisted for his mandatory military service as a public service worker and was discharged on December 9, 2023.
