Kim Hee Sun saved Lee Sung Gye's life.
On 11th, the new episode of SBS drama 'Faith' showed Yoo Eun Soo(Kim Hee Sun) meeting Lee Sung Gye, who built Choson.
Eun Soo found a patient suffering from appendicitis, went to Gi Cheol(Yoo Oh Sung) to get her surgery tools, and saved him.
Afterwards, Eun Soo went to the palace to examine Princess Nokuk(Park Se Young), and found out that the patient's name was Lee Sung Gye.
Eun Soo said, "No way. The Lee Sung Gye from the history book? If it wasn't me, would you have passed away? If I didn't cure the kid, would he have died?", and fell in a major shock that she can change the history.
Especially, when Choi Young came after finding out that Cheon Eum Ja(Sung Hoon) was tracing her, she said, "I don't know much, but I know I'm not supposed to change the history. That's why I was being much more careful, but do you know who the patient was? I saved someone who will kill you in the future."
On the other hand, Eun Soo fell in a confusion after finding her name written on Hwa Ta's relic.
