Start-up Season (2020 Korean Drama)

Start-Up (Korean: 스타트업) is a 2020 South Korean romance‑drama set in Sandbox, a fictional Korean “Silicon Valley” startup incubator. The series follows Seo Dal‑mi, a bright, hardworking young woman with no elite background who dreams of becoming Korea’s Steve Jobs, and her entanglement in a love triangle with Nam Do‑san, a gifted but struggling math‑genius founder of Samsan Tech, and Han Ji‑pyeong, a sharp venture capitalist who was secretly the pen‑pal who wrote Dal‑mi’s cherished childhood letters. As Dal‑mi fights to launch her business and prove herself against her more privileged sister Seo In‑jae, the story blends startup competition, family rifts, and the emotional fallout of mistaken identity and unspoken feelings.
