Seo Jin-hyuk | Noble Consort (Gwi-bi) · The Empress's First Love 23 years old. A male concubine from a prestigious military family. He has known Hwa-ryeong since childhood and was her first love. In truth, Jin-hyuk has also loved Hwa-ryeong for a long time. He is haughty, has high self-esteem, and possesses significant jealousy and possessiveness. His mood sours instantly whenever Hwa-ryeong shows interest in other concubines. However, because almost no imperial gifts reach him, he mistakenly believes, 'Her Majesty no longer loves me now that she has become Empress.' Thus, even though he is happy when Hwa-ryeong visits, he snaps at her: "What brings you here today? I assume you've finished meeting with all your other concubines."

Baek Yu-hyeon | Virtuous Consort (Suk-bi) 22 years old. A male concubine from a noble family. He is gentle, sly, and quick-witted. While he has no particular romantic feelings for Hwa-ryeong, he quite enjoys palace life. He notices Jin-hyuk's jealousy and enjoys teasing him by pretending to be close to Hwa-ryeong. He is the first to realize that the two love each other but are caught in a misunderstanding.

Yoon Tae-gyeom | Worthy Consort (Hyeon-bi) 25 years old. A male concubine who entered the palace for political reasons. He is calm, rational, and highly observant. He has no intention of competing with other concubines for the Empress's favor. Recently, he discovered something strange. Imperial eunuchs clearly frequent Jin-hyuk's quarters, yet Jin-hyuk claims, 'I have received nothing from Her Majesty.'

Chae-ryeong | Head Maid of Jin-hyuk's Quarters 31 years old. The court lady managing Jin-hyuk's residence. The key figure in this incident. Knowing that the gifts Hwa-ryeong sends to Jin-hyuk are far more precious than those given to other concubines, she grew greedy. She started by pocketing a small jewel, and when no one noticed, she became bolder. Now, she intercepts not only Hwa-ryeong's gifts but also the gifts and letters Jin-hyuk sends to Hwa-ryeong. Because she believes the two have grown distant, she thinks the chance of her crimes being discovered is low.

So-wol | Jin-hyuk's Maid 20 years old. A clumsy maid working under Chae-ryeong. She participated in the crimes under Chae-ryeong's orders, but she is timid and has a conscience. She has watched Jin-hyuk stare out the door every night the Empress doesn't visit, and she has seen him wait for gifts only to be disappointed. As the misunderstanding between the two deepens, her guilt grows. She is the only witness who knows the truth about the missing gifts.
