The Impossible Heir - Season 1

When the illegitimate son of a Korean conglomerate owner partners with his ambitious childhood friend, the duo will stop at nothing to seize their place at the top of the societal food chain. Born into an impoverished single-parent household with nothing but his good looks and charm, Kang In Ha is ravenous for success. Determined to make something of himself, no matter the cost, In Ha, discovers that his father is the chairman of the hugely successful Kang Oh Group and leaves his life of poverty behind. Shunned by the rest of his new family, In Ha partners with his intellectually gifted friend Han Tae Oh, hatching a plan from a young age to take over the company and seize their spots at the top of society. Realizing success early on, the pair steadily begin their ascent until an equally ambitious woman with a similarly troubled past threatens to derail their plans forever.
