Military school student Su Keqing lost her footing and fell from a tree during a large-scale practical exercise organized by the school. The reason was that she was absent-mindedly thinking about her ex-boyfriend, the boyfriend who dumped her. I thought I would fall half dead, but unexpectedly, I accidentally traveled through time and fell into the arms of a beautiful man. Later, I learned that this handsome man turned out to be a prince, and his brother was an emperor. What was even more ridiculous was that the emperor's brother was exactly the same as his ex-boyfriend... Can Qing continue to love her ex-boyfriend?
