'You Who Came From the Stars' is the work of 'Deep-Rooted Tree's PD Jang Tae Yoo and 'You Who Rolled In Unexpectedly's writer Park Ji Eun. The drama will portray an interesting story of an alien man, Do Min Jun (Kim Soo Hyun), with great looks and out-of-this-world abilities, who has been living on Earth since the Joseon dynasty. Four centuries later, he falls in love with an actress named Chun Song Yi (Jun Ji Hyun).

'You Who Came From the Stars' will premiere following 'Heirs' on December 18! Check out the teasers while you wait!
