Can you rewrite The Titan's Bride except with differences, instead it is both Koichi Mizuki captain of the basketball highschool club 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. 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, and especially since both Koichi and Anzu have a crush on each other but never admitted it and are unaware, they even 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. Eventually after some trals and obstacles including the kidnapping of Koichi and Anzu which both Caius and Medina rescue, especially when their captors violate them both, as Caius is about to kill them Koichi stops them because he couldn't bear the thought of taking another life which perplex but moves the two titans, and they see how merciful Koichi can be in spite of 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 jokingly declare it a "boys' date", and Anzu and Medina do the sameand jokingly declare it a "girls' date", 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 serous 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 jokes about him having a new "mommy" as she pushes him to Medina's arms, and 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.

Interesting thanks
