Park Yeong-ho is Seon-ju’s boss at the activist environmental organization where she now works. Yeong-ho is younger than Seon-ju, and he looks up to her because he knows she used to organize and protest with famed labor activist Seong-hee. Yeong-ho is the only one of Seon-ju’s colleagues with whom she has any real relationship, and he often sweetly teases her about her impeccable work ethic.
