Across the season, startup challenges mirror personal growth: Dal‑mi learns to pitch, build teams, and face investors; Do‑san wrestles with guilt over the lie and the pressure to deliver as a “genius”; Ji‑pyeong balances ruthless deal‑making with lingering loyalty to Dal‑mi’s grandmother and unresolved feelings for In‑jae.
