Maybe a Fake Gintama - Chapter 4: [Samurai] and [Bushido]

In the middle of a deserted island, a small boy wakes up with two sets of memories: one from his few years of life and the other from a man who lived to adulthood and achieved great things. When he least expected it, a powerful master appeared on the island and took him in as a disciple, revealing a shocking fact: magic exists in that world, and, thanks to it, humanity managed to conquer the galaxy.

The day she transmigrated it, she was already the wife of two men. She later became the Queen of the country. Her life has been cherished by seven men.

After self-sacrificing, Yuri transmigrates from an apocalyptic to an interstellar era, inhabiting a disabled girl's body. She enters a joint marriage with a similarly disabled SSS-tier alpha, gaining a share in an ore planet. Determined to help her husband regain leg function and reclaim his SSS-rank, their journey together unfolds.

This is the stories of two different people from two different worlds (literally)

She was raised in love, while he was raised in hate

Her birth was celebrated, while he was despised

She was protected, while he was abused everyday.

She is gentle, warm and kind, while he is cold, cruel and vicious

But with the twist of fate, their world collided. They will learn from each other.

He will teach her to be hopeful and live for herself, while she will teach him the joys of Friendship and Love

Together they will learn to understand each other, accept each other and love each other, and soon their love will change the fate of the world

Princess: Can you stop staring at me while I'm sleeping?

The Lord: I can't…

The Princess: Are you gonna stare at me the whole night?

The Lord: Yes!

The Princess: Can you at least act like a normal man who will take advantage of a maiden while in her room.

The Lord: …this Lord would oblige

The Princess: WAIT… This princess is kidding, just kidding, wait…!
