Kim Seong-jeong
Kim Seong-jeong (김성정) is part of the new actor wave using musical-theatre discipline as a springboard into television. His official YY Entertainment profile traces that public start back to the 2021 stage production of Hadestown, while his screen momentum accelerated with Weak Hero Class 2 on Netflix and Head Over Heels on tvN.
What stands out is the timing. Kim arrived on television just as youth-skewing Korean drama kept moving harder toward streaming and fandom crossover, which gave him space to land memorable supporting parts before the audience had fully fixed him in one lane. That flexibility now carries into Disney+'s The Miracles of the Namiya General Store, where he joins another project with real platform weight.
He is still early in the climb, but the foundation is strong: agency-backed visibility, an official Instagram account, and credits spanning stage and screen. For HITKULTR, Kim Seong-jeong reads like an actor whose next two or three titles will decide how fast the broader market catches up.
