Because Shin Chae Kyung's grandfather was an old friend of the king, Shin Chae Kyung became the crown prince's concubine. However, the Crown Prince was concerned about Shin Chae Kyung's various behaviors (including but not limited to kissing other people while on a business trip in Thailand, and never returning Caijing's calls, which caused Caijing to fall ill, and then the prince kissed other people. The photo was reported, Chae Kyung was gossiped about and Chae Kyung fainted) which made her disgusted. Yul Jun's arrival broke her life, but she found that Lu Jun only used (and possessed) her. Shen Chae Kyung no longer wanted to live in the eyes of men, so Shin Chae Kyung became the emperor through various forces.
