Lily

Who is Chenyu?
Chenyu is a minor but memorable character. He holds the position of chief eunuch in the imperial palace. His main duties are to manage the palace servants, supervise the harem, and maintain order within the palace premises.
Character and appearance
Chenyu has a rather distinctive appearance: he is a large, muscular man with a shaved head and the characteristic facial features typical of eunuchs (the lack of hair on his head, his particular build, and his demeanor). By nature, he is reserved, loyal to the emperor, and wielding considerable influence at court.
Role in the plot
Chengyu plays a vital role in the intrigues unfolding around the main character, the "court butterfly" Reirin. After Reirin's rival, the wily "court rat" Keigetsu, magically swaps bodies with her, Chengyu finds himself caught in a whirlwind of events. He is forced to adapt to the new reality, navigating palace factions and trying to maintain his position.
Interesting details
Status: As a eunuch, Chenyu is deprived of many rights and freedoms, but still has enormous influence and access to the emperor.
Influence: He is closely connected to key political figures at court and is involved in complex palace games.
Character Development: Throughout the story, Chenyu demonstrates flexibility and the ability to adapt to changing circumstances, making him one of those characters whose evolution is interesting to watch.

Basic information
Status: Crown Prince of the Kingdom of A.
Relationships: Chenyu's elder brother.
Character and traits
Yaoming is a complex person, combining external severity with an inner capacity for change. Here are his key traits:
Strict and principled: he zealously monitors order at court and does not tolerate violations of etiquette.
Imperious and ambitious: used to getting his way.
Reflective ability: beneath the tough exterior lies the ability to acknowledge one's own mistakes.
Role in the plot
Initially, Yaoming considers Linglin his fiancée. The turning point comes after a magical body swap between Linglin and her rival, Huiyue (nicknamed "Rat" in the anime). At first, the prince, blinded by his feelings, is unaware of the substitution and continues to consider "Linglin" (i.e., Huiyue) his chosen one. However, his "fiancée's" strange behavior begins to raise his doubts.

Who is she?
Qingjia Jin (金清佳 in Japanese) is a minor character. She belongs to one of the five noble families whose representatives make up the maiden court at the imperial palace.
Role in the plot
Unlike the main characters (Reirin/Linglin and Keigetsu/Huiyue), who swapped bodies due to magic, Qingja Jin doesn't participate in the main exchange. Her role is more background: she's part of the palace setting where the events unfold.
Character and traits
There's almost no detailed information about Qingjia Jin's character in open sources. One can only assume that, like many court ladies, she adheres to strict rules of etiquette and follows palace traditions.

Appearance and status
Zhu Huiyue is one of five girls being groomed in the palace as potential brides for Crown Prince Yun Yaoming. Due to her lowly birth, sharp temper, and habit of taking her anger out on the maids, she has been nicknamed the "Palace Rat." She is disliked and shunned within the palace.
Character and motives
Behind her brash and rude exterior lies a deeply wounded nature. As a child, she suffered cruelty at the hands of her mother. After her parents' death, the girl was taken into the care of a noble relative, Zhu Yamei. However, she only formally accepted her, revealing her coldness, and Huiyue never received any warmth or a mentor who could guide her on the right path.
Huiyue constantly suffered from feelings of inferiority, comparing herself to her more successful and beloved rival, Huang Linglin. She was especially envious of Linglin's impeccable reputation and popularity, nicknamed "Court Butterfly" in the palace.
Body-swapping story arc
On the night of the Double Seventh Festival, Huiyue resorted to a forbidden Dao technique and swapped bodies with Huang Linglin. However, her plan backfired: Linglin's body proved fatally weak, and Huiyue nearly died from an illness that her former owner had only managed to overcome with her iron will.
The girls subsequently became close and friends. Huiyue even helped expose Zhu Yamei's plot against Empress Huang Juanxiu.

Biography and status
Origin: Princess of the Huang clan.
Family ties. Niece of Empress Juanxiu.
Role at court. One of five girls traditionally selected to become the future emperor's wives. Courtiers nicknamed her "the beautiful butterfly of the imperial court" for her beauty, intelligence, and kind nature. The crown prince clearly singled her out among the other candidates.

Character and personality
Fragile health. Since childhood, she suffered from serious illnesses, which made her constantly feel like a prisoner.
Iron Will. Despite her physical weakness, Linglin possessed an unyielding character and faced all difficulties with a smile.
Optimism and determination. Finding a healthy body was a true gift for her, and she wasn't about to give up even under the threat of execution.
Plot role
A key plot twist occurs during the Lantern Festival. Zhu Huiyue's jealous rival (nicknamed the "Palace Rat") sets a trap: she attacks Linglin and pushes her off the veranda into the pool. A magical incident results in the two girls switching bodies.
Now Linglin's consciousness finds itself in the body of the hated Zhu Huiyue, and she herself is in the body of a victim, despised by everyone in the palace. Moreover, due to a spell cast upon her, she cannot openly speak of what happened to her. She is accused of a crime she did not commit and faces the death penalty.
However, Linglin doesn't see herself as a victim. She uses her wit and steeled will to unravel palace intrigues, find evidence of her innocence, and ultimately change the way others view her and Huiyue.

Despair nearly breaks Lily, but the situation changes when Kou Reirin enters Keigetsu's body (known as the "court rat"). It is Lily who first notices the substitution: Reirin's personality change is too extreme, and her villainous behavior is too forced and childish. When another court lady, Kou Tousetsu, appears and confirms her suspicions, Lily laughs at the situation, but is simultaneously saddened by the realization that the exchange may end.

Later, Lily is surprised to realize that Reirin's genuine kindness has changed her true owner for the better.
At the same time, Lily is often irritated by both Keigetsu's cruel treatment (who later displays tsundere traits) and Reirin's overly optimistic nature - both poles of interaction leave her emotionally drained.

Lily (莉莉, Rīrī) — all about the character
Lily is one of the key female characters in the anime "Even though I'm a Talentless Villainess: The Tale of How a Butterfly and a Rat Traded Places in the Maiden's Court" (Futsutsuka na Akujo dewa Gozaimasu ga: Suuguu Chouso Torikae Den). She is the personal courtier of Shu Keigetsu, the main "villain" of the story. Despite her minor role, Lily undergoes one of the most touching developmental arcs in the entire series.
Appearance
Lily inherited her mother's chestnut-red hair, amber eyes, and strong body—the result of lessons in Sogdian whirlwind dancing. She wears most of her hair in two small buns on top of her head, with the rest hanging loose. Her face is framed by two fluffy strands in front and a side-swept fringe.
Initially, Lily wore light red, simple clothing, denoting her low status within the Shu clan. Later, thanks to Kou Reirin, her wardrobe changed to darker red outfits for important occasions, befitting her new position as the chief attendant of a high-ranking lady.
Origin and status
Lily is an illegitimate child: her father is a court official from the Shu clan, and her mother is a foreign dancer. Because of this status, her father refused to accept her into the clan's main family. Instead, Lily was sent to work at the Court of the Virgins, where she aspired to obtain an official title. The only material inheritance she received from her father was access to his five classic books.
Role in the plot
Lily is originally a low-ranking court lady and Shu Keigetsu's chief assistant.
Personality
Despite her low status, Lily has a good-natured personality from the start. She struggles daily with being looked down upon because of her background and tries to be proud of herself by honoring her mother's legacy. However, the constant malice of those around her deeply wounds her.
