Can you rewrite The Titan's Bride except with differences, instead it is both Koichi Mizuki a graduated senior and was previously the captain of the Basketball Club for 3 years and received excellent grades at Touou High and Anzu Tanaka the female manager of the basketball highschool club, that get sent to another world by Caius the Titan Prince of Tildant, but he doesn't know which one is his bride, the male Koichi or the female Anzu. Kouichi has a very tender and heart-warming personality towards others, both inside and outside of school, on the other hand, Kouichi can also be stubborn when it comes to not wanting to go along with certain decisions made by others without his consent. Anzu has a very sincere and goodwill-like personality towards her peers in the Basketball Club and those outside of it, Anzu seemed to get along with Koichi very well and even thanked him for his hard-work and support during the last three years by giving him a message ball from everyone in the club. Caius has a open-minded and devoted personality towards his fellow subjects and foreigners. When it comes to someone close to him, Caius is very kindhearted and cherishing towards that individual. However, Caius can also be serious, demanding, and violent to those that don't listen and harming the one's close to him. He showed determination in never giving up researching how to learn summoning magic as a similar attitude was shown in his desire to gain the throne and his beloved. Both Koichi and Anzu are surprised and shocked about their predicament and also by the massive size of the prince and the race of Titans that dwarf the two and the structure of the buildings they are in, even more shocked and dismayed by the prospect of both of them getting married to a prince, especially Koichi and at first slighted and demands he sends them both back, but can't due to consequences from use of their magic, ie the circumstances of Anzu's and Koichi's presence end up poking a hole in the dimensional "wall" between their home world and Eustil that keeps the worlds separate and stable and it takes one month for it to repair itself, but it also means they would need to make a very important decision: leave Caius behind and return home, or form a contract that would also essentially rewrite history to where both Koichi and Anzu died young in their original home, and especially since both Koichi and Anzu have a crush on each other but never admitted it and are unaware, they decided to go as far as saying they are engaged to each other which Caius puts to the test, by seducing and charming them on separate occasions and surprisingly it works on them which bewilders and confuses Koichi. Eventually Medina, female Titan from Tildant and ex-fiancee of Prince Caius gets involved causing a rift on the three. Although sometimes viewed by others as being cold-hearted and devious, Medina is very genuine and thoughtful to those that are close to her. But one day both Koichi and Anzu get kidnapped some hostle wolfmen which both Caius and Medina come to the rescue, while their captors violate them both, and as Caius is about to kill them Koichi stops them because he couldn't bear the thought of taking another life which perplexes but moves the two titans, and both Titans and Anzu see how merciful Koichi can be in spite of the wrong that was done to him, gradually after their recovery Koichi and Anzu become accepting of the world they are in and those around, Koichi even apologizes to Caius for his previous behavior and attitude, and Caius gets engaged to Anzu and Koichi to Medina, and the night before they are officially engaged to their respective partners, Caius and Koichi spend a night together, and Anzu and Medina do the same, where they learn about each other and each begin to understand why they fell for each other and end it with Koichi telling Caius to take good care of Anzu the best manager in the world, as Anzu tells Medina a similar thing and even jokingly tells her to be both a mom and a wife to Koichi but it takes a bit serious turn when she reveals how close Koichi was to his mom, and the accident that killed her. Which Caius learns and uses his magic to summon the ghost of his mom to see one last time to have a moment where she wishes him well and she jokes to Koichi about him having a new "mommy" as she pushes him to Medina's arms, and Koichi's mom tells Medina to make her son onto a fine daddy. After that both Anzu and Koichi become a Titan's Bride and a Titan's Groom respectively as Anzu is engaged to Caius and Koichi to Medina. How would this alternate version play out, how do these alternate scenarios go and how does it end? Can you write extra chapters of how these characters interact with one another?
