Lee Min Ho and Kim Hee Sun are making the viewers desperate for more romance.

On the Monday episode of SBS Mon/Tues drama "Great Doctor," Choi Young (Lee Min Ho) tells Eun Soo (Kim Hee Sun) that he'll stay by her side for the time that she has left. He promises her that he'll make her laugh. 

Until now, "Great Doctor" kept the audiences' hearts breaking with the romantic storyline between Eun Soo who traveled through time to get to Koryo and Choi Young, a historically famous warrior.

The two actors showed off a side that they hadn't shown before, being in a historical drama. They brought interesting nuances of time travel and the differences that arise between radically different generations. 

With Eun Soo currently poisoned and with no way to treat her, they are waiting for the doors to the sky to open and to send her back to her time. 

The finale will air tomorrow.
