In "Scholar Walking in the Night" Jo Yang Sun (played by Lee Yoo Bi) was pressured from the authorities.

On the 9th episode of MBC Wednesday/Thursday drama "Scholar Walking in the Night" broadcast on August 5th, Jo Yang Sun was told that she would need to get a false confession about the vulgar teacher.

To Jo Saeng (played by Jung Kyu Soo) who had lost his consciousness after severe torture, he said, "Dad. My dad. Please watch over him. He wasn't able to get up. Dad" and cried. Then, Jo Yang Sun's torturer came over. He said, "Dad will save you. If I say that I'm going to confess and going to be the vulgar teacher" he proposed.

Jo Yang Sun repeatedly said, "I'm not the vulgar teacher." Nonetheless, finding out about the identity of the vampire, he said, "Do vampires really exist?" and was surprised. At that moment, he said, "If you're dead, then we can all live. Not only your father who has died but also the citizens." With that, Jo Yang Sun choked up. He said, "If I'm the only one who dies, then will you be able to save it?" and shed tears alone as he talked to himself.
