Gongju, a student of KyungHee University, is on a class trip to the museum for her History project. There, she learned about the history of the Joseon Dynasty and also about a royal soldier who was accused of abandoning his duties. Of course, History was her most boring subject ever. One night, while she was researching about the Joseon Dynasty, she felt asleep. When she woke up, she found herself back in 1400 during the Joseon Dynasty. She also met a soldier she has seen in the museum. The soldier tries his best to help her get back to the present time. When Gongju heard he was accused, she tries her best to save him from his death. Will they be able to succeed on their task? Main Characters: Lee Gongju (OC)- a student of KyungHee - doesnt have interest in History - was taken back to the Joseon Dynasty Lee Donghae- a soldier to the royal family- about to be punished to death for abandoning his duties later- has a crush on Gongju- at the end of the story, he portrays as a new student in KyungHee  Minor Characters: Kim Ryeowook- another student of KyungHee- good friend to Gongju Kang Minhyuk- another soldier to the royal family- dislikes Donghae a lot in the Joseon dynasty- portrays as one of the popular guys in KyungHee - has a huge crush on Gongju Tiffany Hwang- Gongjus best friend  A/N:Ryeowook and Tiffany are the only characters that do not appear in the Joseon Dynasty.
