Lee Min Ho gave Kim Hee Sun an aspirin pill through a kiss.
On October 29th, during episode 23 of SBS Monday-Tuesday drama 'Faith', Eun Su (played by Kim Hee Sun) decided to drink poison to get rid of the poison in her body.
In the episode, Choi Young was shocked at Eun Su's decision. He yelled, "You're going to drink poison to defeat the poison in your body?! What are your chances of succeeding?!" At this, Eun Su said, "I'm not sure since I'm the first one to attempt this. I can't just sit still and do nothing because once the fever starts, it's all over."
Choi Young bitterly replied, "During the time it takes for heaven's gate to open, I have nothing else that I can do for you. Even the part where I said I would make you smile... How can you stare at me like everything is all right?"
After Eun Su comfortingly said, "I know this could be my last so how could I wait for the end in tears? I believe that I will be okay so don't worry," she drank the poison. Immediately, she showed signs of fever so Choi Young stayed by her side to look after her.
Choi Young discovered the bottle of aspirin she once gave to him and remembered what Eun Su had said about it. Choi Young chewed the aspirin pill and gave it to her through a kiss.
