Interstellar Marriage: My Key Girl

Sweet pet + interstellar + strong female + two-way growth Diso, the arrogant and willful pure-blood royal family of Tuzeska, traveled across the stars in a legendary starship inherited from his ancestors. He originally wanted to explore the universe as he pleased. During a chance encounter on an abandoned ancient space station, he picked up Evelin, a frail black-haired human girl who had lost her memory. Everyone thought she was a little burden who needed to rely on him, but only Diso knew: This seemingly frail girl holds the energy key to unlock the ancient arsenal. Her unique purifying spiritual power can tame all interstellar machinery and repair energy disorders in the universe. She is also the only inheritor of pure human genetic heritage that has been dusted for decades. The remaining forces of Rufa and the careerists in the Dark Star Territory are chasing after him step by step, trying to seize the key to restart the forbidden shuttle technology and disrupt the entire galaxy. The blond-haired, red-eyed dragon boy who used to be extremely possessive and didn't understand love put away his carelessness and piloted the Crow to fight for her against pursuers from all over the galaxy; The cowardly and sensitive amnesiac girl slowly loses her vulnerability, awakens the spiritual power that shakes the universe, appeases his violent racial nature, and works side by side with him to expose the interstellar conspiracy. From a "found possession" to the only bond in this life, the growth and preference of the tsundere Tuzeska are all dedicated to his little human girl.
