Can you rewrite The Titan’s
Bride except with differences,
instead of Koichi summoned 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.
Can you rewrite it as such: After a great basketball game at Touou High,
Koichi is relieved it is finished, he reads the basketball
with everyone’s signature to remember everyone,
and imagines what it would be to go
on a date with Anzu, instead of fantasizing,
he calls over Anzu to visit him and they talk while at
his bedroom, where something happens, when they here a voice calling them,
and they both find themselves transported to another world.
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
so either of them can’t marry Caius,
which Caius puts to the test,
by seducing and charming them on separate occasions
and surprisingly it works on
them which bewilders, slights but even
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 hostile 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, though both traumatized, both Titans comfort the two humans, Medina even cradles Koichi like a mother cradling her baby, but as Koichi falls unconscious he utters the word “mom” while shedding a few tears, which bewilders Medina
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,
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 strikes Medina,
and makes her realize Koichi's reaction then when both
Titans came to their rescue 
Which Caius decides to use 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?
