Synopsis
“First Man” Korean drama tells the story of twin sisters O Jang Mi and Ma Seo Rin, who live very different lives. Jang Mi is kind and honest, while Seo Rin is a spoiled chaebol heiress who always gets her way. When their lives suddenly mix, they begin to step into each other’s world and discover secrets, new love, and problems they never expected.
Their story also connects with two brothers—Baek Ho, a gentle lawyer, and Jun Ho, a strict chef with a soft heart—both drawn to Jang Mi. At the same time, Jin Hong Ju becomes jealous of Jang Mi, and Chae Hwa Yeong, a former star with strong ambition, tries to take power for herself. As truth comes out and feelings clash, the twins must face each other and the tough world around them.
