Korean actors Lee Jong-suk and Lee Sang-yeob were spotted to strike sparks off at each other in 'While You Were Sleeping'.

On September 25, the production company of SBS new drama 'While You Were Sleeping' released new set of stills which seem to hint at the two actors' extraordinary relationship. 
Earlier from its third teaser, Jae-chan(played by Lee Jong-suk) and Yoo-bum(played by Lee Sang-yeob) have shown special relationship between the two. They first met as student and tutor, then later meet as a prosecutor and a criminal defense lawyer. 
However, as their new stills show how they are glaring at each other, it is making fans curious to know what has happened between the two. 

Jae-chan's childhood memory with Yoo-bum was also shown. Young Jae-chan is looking at his tutor Yoo-bum as if he's scared. In the next photo released, Yoo-bum was spotted to grab Jae-chan's face with two hands creating serious tensions between the two.

Meanwhile, 'While You Were Sleeping' is expected to go on air in two days, on September 27.
