In "Scholar Walking in the Night" Jo Yang Sun (played by Lee Yoo Bi) was resentful of Lee Yoon (played by Choi Kang Chang Min).
On the 10th episode of MBC Wednesday/Thursday drama "Scholar Walking in the Night" (script Jang Hyun Joo, director Lee Sung Joon) broadcast on August 6th Yang Sun had become a slave after the incident involving the vulgar teacher incident. Seeing this, Lee Yoon looked worried and went over to Yang Sun. Yang Sun asked, "Are you sorry?" Lee Yoon said, "Yes." With that, Yang Sun said, "Just be sorry a thousand a million times. You did something to me that you can't erase."
Then again, he said, "Take that sorry heart and go rescue your country and your people. That's what the scandalous vulgar teacher has to do. And never appear in front of me ever again. I don't want to see this." Lee Yoon also said coldly, "Yes. I'll do that. And I'll never appear in front of you." With that, it'll be interesting to see how the rapport of the two improves.
Meanwhile, "Scholar Walking in the Night" is a period drama set in a period where there are vampires. As the plot is wrapped around a scandalous vulgar teacher, it features Lee Joon Ki.
