## Block B and music career
P.O joined Block B, debuting in 2011 with the group's digital single "Do U Wanna B?" alongside Taeil, Bi Beom, Jaehyo, U-Kwon, Park Kyung, and Zico.[2](https://ktrenz.com/article/2026/06/po-block-b-career-profile-2011-debut-2026-lineup) His path into the group was indirect: he was eliminated during the group's first official audition, then received a second chance a year later after losing 10 kg and training intensively to improve his skills.[1](https://kprofiles.com/p-o-block-b-profile-facts/) In a 2011 interview he recalled being dropped while chubby and permed, and resolved to prove the decision wrong.[5](https://bontheblog.wordpress.com/2011/08/18/interview-10asia-p-o/)
Within Block B he served as a sub-rapper, and he formed the sub-unit Bastarz, which released the mini album *Poomhaengjero* in 2015. His first solo release was the mini album *MEN'Z NIGHT* in 2017.[2](https://ktrenz.com/article/2026/06/po-block-b-career-profile-2011-debut-2026-lineup) A 2018 review of his single "소년처럼 (Comme Des Garcons)", released through Seven Seasons on November 11, 2018, noted a contrast with his usual rough-voiced, high-volume group parts: the single moved at a calmer, lower tone, drawing attention to his rapping and autobiographical lyrics.[6](https://idology.kr/11677)
## Acting career
P.O's drama debut came in 2017 in *[Temperature of Love](https://www.edgepedia.org/temperature-of-love)*, credited under his real name Pyo Ji-hoon.[2](https://ktrenz.com/article/2026/06/po-block-b-career-profile-2011-debut-2026-lineup) His screen roles since then include Ji Hyun-joong in tvN's *Hotel del Luna* (2019), Jin Sang-hyeok in *More Than Friends* (JTBC, 2020), Shin Sang in *Mouse* (tvN, 2021), [Control Z](https://www.edgepedia.org/control-z) in *Yumi's Cells S2* (TVING, 2022), and Jeon Eun-ho in *Good Partner* (SBS, 2024); he led the 2023 film *New Normal* as Ki-jin.[2](https://ktrenz.com/article/2026/06/po-block-b-career-profile-2011-debut-2026-lineup) • [3](https://asianwiki.com/P.O)
