Cosmic Conquest: Rosalina turns You into her Husband

Prompt: Write a story of the male human (from real life), encountering Rosalina (from the Mario franchise), who visits Earth and wants to challenge him in a game (an intense sports-like game of some kind), which the man is told that he cannot decline the challenge (since the man has no choice to decline). If the man wins, Rosalina will go to another planet to find a more suitable candidate to be her husband, but if Rosalina wins, she will happily turn the man into her husband (thanks to her magic powers of her wand) and be with her for all eternity; sadly for the man, he lost the game and Rosalina won the game (since the game is only in Rosalina's favor and is completely unfair to the man in the man's point-of-view), so Rosalina is genuinely happy and then transforms the man (with her wand) into her husband. The side effects of turning into with instant clothes change, age change (turning from whatever age the man was into a 25 year old), height progression (changing from an average 5.7-6 foot height to a 7.6 foot height), and mind/mental change (with the man's personalities and memories being completely replaced with new personality and memories of being a royal and polite gentleman (named Polydeuces) who is Rosalina's loyal and loving husband, despite the man's best efforts of fighting his new personality and memories (he's scared of forgetting/losing himself, so he tells himself not to forget, but to no avail, and Rosalina comforts the changing man and says that he's returning to her), making the man completely forget he was an average man of Earth (which he realized was not real), even forgetting that the transformation that just occurred seconds ago, and only remembered that he had always been a gentleman named Polydeuces, which he always knew that this is his real/true self). After the transformation, Rosalina brings Polydeuces with her back home in The Cosmos/Comet Observatory, where Polydeuces remembers having lived ever since he, as a late-stage child, had obtained every powers that Rosalina also has, and he is truly happy about his true self as a powerful sorcerer of The Cosmos/Comet Observatory and Rosalina's affectionate husband (with Rosalina also being affectionate towards him). For the Polydeuces's appearance (after the man turned into him), he is a tall handsome young adult man (taller than Rosalina (who is 7 feet 3 inches tall) due to his 7 foot 6 inch height) dressed in a rather handsome suit, complete with a gray waist coat possessing a tall, white collar, a red neck scarf, a pair of black slacks, and a long black coat with wide tails; he also has a pair of white gloves over his hands and a pair of fancy knee-high brown boots. He has a slim body with very light (almost white) tan skin, while his hair is fiery-auburn in color and tied back with a thin, brown cord, which is styled, with the frontal fringes parting perfectly to the sides of his beautiful face, and he has powerful green eyes. Here are Polydeuces's powers and abilities; Magic (Just like Rosalina, he is extremely skilled in the use of magic. It is unknown how he and Rosalina gained the ability to use magic, as they did not showcase the ability to use magic as children), Force Field Generation (Like Rosalina, he can create force fields. He can surround the Comet Observatory with a huge force field, transforming it into a starship as a form of transportation. Also, if Mario attempts to jump on either Rosalina or Polydeuces, a force field will appear and protect them), Levitation (Like Rosalina and the Lumas, Polydeuces can levitate himself into the air), Flight (Like Rosalina and the Lumas, Polydeuces has the ability to fly), Teleport: (Polydeuces, just like Rosalina, has shown the ability to teleport, at least from Earth to Space), Telepathy (When Mario wakes up in the Mushroom Kingdom after the Lumas throw themselves into the black hole that Bowser's collapsing galaxy created, both Polydeuces and Rosalina speak to Mario via telepathy, telling him that all life carries the essence of stars, even himself), Holograms (Like Rosalina, Polydeuces has shown the ability to create holograms of himself, when she encounters Mario after he defeats Bowser), and Immortality & Eternal Youth (Just like Rosalina, Polydeuces has the appearance of a tall, young person, in Polydeuces's case a man, and has a youthful face and figure, despite being at least one hundred years old) Here is Polydeuces's personality; Polydeuces is shown to be a wise, mature, polite, elegant, royal, loyal, fatherly and kind man, who has made protecting the cosmos his and Rosalina's (his wife) mission in life. He is a loving father figure to the Lumas, caring for his and Rosalina's children diligently. He also showed sorrow for Rosalina's own mother, who apparently died many years before Rosalina met the Lumas. He also uses the phrase "may the stars shine down on you" as a way of saying good luck. A powerful figure, and like Rosalina, Polydeuces has little-to-no fear even in the face of danger, as he threw himself in between Cursa and the Lumas in order to protect them without hesitation. Polydeuces, just like Rosalina, possesses extensive knowledge of the universe and the abilities of the Lumas, as he explains to Mario/Luigi how Lumas are adept at transforming and how they are reborn. Polydeuces, like Rosalina, is ambidextrous, using his right hand for magic, but his left hand holding her wand. He is also adept at dancing, especially waltz, which he performs with Rosalina. There should also be quotes from the characters in this story (including quotes from the man) so we know what they're saying and what they're thinking. Also, it is a POV reader story, so it should not be in an author's point of view (my, I, mine, etc), and it should be from the point of view of the man/reader (you, your, etc).
