Actor Lee Min Ho has been captured fast asleep on the set of his new drama, SBS's 'Faith'.

Several new photos of the actor dressed in his character and busy filming the new drama were shared on Lee Min Ho's official Facebook page.

One in particular, the photo above seemed to really catch the attention of fans. The actor appears utterly exhausted from the long filming hours as he is caught snoozing with his head tilted back and his mouth wide open.

Fans commented, "He must have been extremely tired", "He looks handsome even while he sleeps with his mouth open", "Even the armor looks good on him."

"Faith" is a time-warp, historial fusion drama where a strange man dressed as a warrior from the Koryo Dynasty, played by Lee Min Ho, claims that he is 'here' to take back a plastic surgeon, played by Kim Hee Sun. Lee Min Ho's character, Choi Young, is a skilled and loyal warrior and a man of his word.
