Kim Soo Hyun put on his poker face while playing a game of mahjong in a scene which will take viewers back to the 400-year history of his character Do Min Jun. He hides his identity as a college professor with a cute wavy hairdo and glasses that help him pull off the hot nerd look.

'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).

The drama is set to premiere following the conclusion of 'Heirs' on December 18! Also check out the BTS video of Kim Soo Hyun and Jun Ji Hyun's poster shoot below!
