After Rival Twin Guides Switched Souls

I'm not good at writing blurbs, so here's a simple outline to start with:

Twin red and white roses. Their quantum beasts are snakes.

Gentle, calculating white-cut-black guide seme x Handsome catlike sentinels (tigers, lions, and other feline types)

Cool, sharp-tongued, super-S guide seme x Handsome puppy-like sentinels (wolves and other canine types)

1. Humanity is wiped out due to radiation and other causes.

The few remaining voyagers settle in a place billions of light-years from the stars they once knew. During their exploration, some humans evolve...

Guides and sentinels emerge.

The voyagers split into two factions.

The Empire values order and life, and lives high in the sky.

The Alliance values freedom and strength, and lives on the ground.

The two sides are hostile to each other, but with Blue Star civilization lost, the minds of the last surviving humans are also beginning to collapse.

On an otherwise ordinary day,

the life-observation cameras placed across Blue Star before the voyage suddenly switch on...

and transmit images showing signs of life.

The Empire and the Alliance reach an agreement and prepare to send their finest guide-sentinel pairs back to the dangerous Blue Star to search for humanity's lost civilization.

2. At a special guide-sentinel academy,

there are two high-level guides known as the red and white roses. But because the Empire and Alliance are enemies, they have no contact with each other.

The Alliance's gentle, beautiful white rose excels at mental healing.

The Empire's cool, handsome red rose excels at mental attacks.

In the Empire, guides are rare and highly valued. The catlike squad leader is a high-level sentinel;

in the Alliance, strength is prized above all, and the puppy-like squad leader is a dark sentinel.

The catlike sentinel has a mild temperament but needs more mental soothing. The red rose's abilities are insufficient to resolve the problem with surface-level soothing. If they use deep soothing, the attack-type guide has to take the receiving role for it to work.

The puppy-like sentinel is ill-tempered and refuses to be controlled, relying on his status as a dark sentinel. He's not interested in the white rose and prefers the strong. Over time, the healing-type white rose will also have to take the receiving role to resolve the problem.

On the starship heading to Blue Star, the red and white roses meet. In a wormhole, their souls inexplicably switch bodies.

They have identical quantum beasts, highly overlapping mental energy, and can communicate mentally with the quantum beasts in their minds.

They discover that they are twins.

So, until they find a way to switch back, they decide to stay in each other's bodies and continue their mission.
