※This article contains spoilers. JTBC TV series "Not a Hero" EP12 (viewer rating 4.9%) features Jang Ki Yong and Da Hye.
On the day of Ina's (Park Soi) dance contest, Da Hye sees Gi Joo's outfit and says, "When I told you that Ina was locked up in the warehouse, you were wearing the same outfit."
"Da Hye wondered. Ki Joo stood up as if he had realized something, and Da Hye followed him and felt his neck. "It's thinner than yesterday. That's why you're in a hurry, you don't have much time," she said. "I'll do it last.
Am I trying to do what I should be doing? Is it inevitable after all... is it an unavoidable fate?" Gi-joo replied, "That's absolutely not the case. I don't know why or how I ended up at that time.
I don't know if I'll end up going there because of my mother's dreams. I've willingly chosen to go and save you. Not because I have no choice, but because I want to.
Da Hye hugged Gi Joo, and Gi Joo said, "So promise me. Don't ever deny the choices you've made up until now. Keep making choices. You can't change the future.
If you can do that, you can create your future next. Don't let bad dreams get you down, and make sure you illuminate your future," he said, kissing Da-hye and running off, saying, "I'll be right there."
