Mederos

Mederos is the het ship between Medea Solon and Eros Orna Vasilios from the Your Throne fandom.

Beginning
As children of the most powerful duchy and the royal family respectively, Medea and Eros were set up to be engaged in their teenage years. Though the two never harbored any genuine feelings for each other at that time, Medea was happy that she could rise to a position higher than her abusive father.

However, Eros, interested in becoming a god, needed Psyche Callista to be his fiancé for the sake of his plans. He decided to hold a Crown Princess contest between Medea and Psyche. Although Medea surpassed Psyche in all aspects of the contest, Eros chose Psyche in the end and manipulated public opinion to support his decision. From then on, Medea resented Psyche for taking away the Crown Princess position from her.

A year later, the two women made a wish that would result in them switching bodies. Medea is gleeful that she got to take everything from Psyche, and continued to act as Psyche to secure her place in the throne. Though Medea soon realizes that Eros doesn't love Psyche at all like he claims to; He despises her. Medea sees his true colors when Eros locks her in Psyche's basement, under the guise of protecting her. Eros eventually released Medea for his birthday banquet.

Birthday Banquet
At the banquet, Medea is led to a secluded part of the garden, where Eros's knights then move to assassinate "Psyche." She realizes that Eros intended to kill Psyche from the start in order to gain her divine power. Held back by Psyche's weaker body, Medea is on the verge of death by the time Psyche and Helio arrive. In her unconscious state, Medea resolves to take control of fate and get revenge on her and Psyche's real enemy: Eros. When she wakes up, she whispers to Psyche that she will kill Eros. In an injured state, Medea arrives back at the banquet in front of the crowd, shocking Eros. She insinuates that Eros is the one who attempted to kill her that night, though Eros is able to lead the public to believe that the perpetrator impersonated him to lead her to the garden.

Post-Banquet
After the banquet, Psyche sustains a broken leg while attempting to avoid an arranged marriage set up by Medea's father. That night, Eros visits "Medea"'s chambers unannounced. Psyche's confidence crumbles when faced with the one who tried to kill her, and she is unable to mimic Medea's stoic demeanor. When seeing "Medea" in a more vulnerable and submissive state, Eros falls in love with Medea.

A few days later, Eros visits Medea and asks her to heal an injured bird with her divine power. Medea claims that it is too late to save the bird, but Eros doesn't believe her. Thinking "Psyche" had temporarily lost her divinity, he moves to lock her in the basement until she regains her power. In that same moment, Psyche figures out how to switch bodies back with Medea, and so they return to their original bodies.

Trial Arc
Medea realizes that because she is the sole heir to the House of Solon, she does not need to become Crown Princess to rise above her father. In her plan to succeed her father, Medea spreads a rumor that she’ll kill her father and plans to hold a trial exposing what he has done. Eros invites Medea to the palace, to which Medea assumes that he will be discussing the trial. She is confused when Eros treats it more like a romantic date. Eros then proposes that Medea let him conduct the trial instead, and in return she can become his Crown Princess in three months. He then kisses Medea, to her shock and disgust. She figures out in that moment that Eros thinks Medea is in love with him because he met with Psyche when their bodies were switched. Medea denies his request, putting on a bit of a heartbroken act about not wanting to be discarded by him a second time. Medea makes a false promise that she will be his Crown Princess, planning to betray Eros like she was once betrayed. That night, Medea vomits.

Afterwards, Medea is mainly in conflict with her father, Thesion Solon, where she ends up getting lethally poisoned. Thesion sends Medea away to let her die, though soon afterwards Eros suddenly visits the Solon Manor looking for Medea. A servant admits what Thesion did to Medea, enraging Eros. Eros puts Thesion in prison to stay until the trial, and then looks across the empire for Medea. Unbeknownst to him, Medea and Psyche had switched bodies so Psyche could heal Medea from the poison. Eros finds "Medea" and embraces her. He gives her a luxurious room in the palace to stay until the start of the trial.

Right before the trial, Medea meets with Eros. She says not to pity the Solons, as her father will be executed anyway. Eros laughs at how Medea easily accepts her father's death, saying they are alike in that regard. Medea silently hates that Eros considers them similar. She requests Eros to support the Reformists in the trial, because if they support her and she becomes Empress, the Reformists will become a powerful faction of support for the Imperial Family. Medea makes this out to be a cautious request for her to become Empress. Eros hugs her, saying he enjoys how timid and anxious Medea is around him. Later, Medea also requests him to bring an audience of people that lived around the border during the war, who generally have a strong sense of loyalty. Eros is curious as to how she'll use this audience.

Visual Novel
In the visual novel, Medea is the main protagonist, and Eros is one of her potential love interests with a secret route.

Fanon
Mederos is the most controversial ship in the fandom due to its problematic nature. Despite this, some like to imagine that in an alternate universe, she and Eros would be an unstoppable power couple. While not very popular as a romantic ship, most fans appreciate Eros as the main villain who can match Medea in terms of scheming. There has been some debate about whether making Eros in love with Medea is a good writing decision.

Another controversial writing decision was making Medea start sleeping with Eros. Even if it was for the sake of deceiving him, a lot of fans believe it to be a betrayal to Medea’s character as well as the feminist themes prevalent in the beginning of the story. This was a big catalyst for many people to stop reading the story, considering it an all-time low in a plot that has been declining in quality for a long time. The scenes of Medea and Eros in bed have also been criticized for pointless fan service, bad anatomy, as well as unrealistic depictions of hickeys. Most notably, a Tweet reacting to one of these scenes got over 9k quote retweets from fans and non-fans alike criticizing this plot point.

Trivia

 * Like the other main characters, Medea and Eros's names are derived from Greek mythology. Eros's name in Korean, Iaros (이아로스 ialoseu), appears to be a combination of the names Iason and Eros, as "Eros" would normally be translated as 에로스 eloseu.
 * In Greek mythology, Iason (or Jason), was the husband of Medea until he abandoned her for another woman. Medea gets revenge by killing her children and Iason's new wife. This parallels the beginning of Your Throne.
