Despite the stopping of Jin Se Yeon, Lee Jong Suk saved Chun Ho Jin in the last episode of "Dr. Stranger".
On the 19th episode of SBS Monday/Tuesday drama "Dr. Stranger" broadcast on July 8th, Park Hoon (played by Lee Jong Suk) saved the life of the prime minister Jang Suk Joo (played by Chun Ho Jin) and ended the series.
The conspiracy was no longer valid but Jang Suk Joo made a deal with the president to remain as prime minister. Afterwards, he asked the president to hand over Park Hoon and Seung Hee. The president betrayed Park Hoon and allowed this. As Park Hoon and Seung Hee were in a risky position, Cha JIn Soo shot Jang Suk Joo.
Here, Park Hoon attempted to save Jang Suk Joo but Seung Hee said otherwise. She said that they'd be at risk and his mother too would suffer if Jang Suk Joo were alive.
Meanwhile, "Dr. Stranger" is about a genius doctor Lee Jong Suk that was born in South Korea but raised in North Korea and his conflict against the most elite doctor of Korea, Park Hae Jin. The two of them face the greatest conspiracy in a medical drama and fusion drama that ended in twenty episodes.
