My Inheritance Is a Disabled Merman [Interstellar]

Not long after Xi Jin was forced to retire due to an injury, her father passed away. She had no choice but to return to the home planet to handle the family affairs.

Along with inheriting a manor and several other assets, she also took on a huge headache: a sickly, disabled mermaid.

Looking at the mermaid girl, who seemed only seventeen or eighteen, with her youthful face, frail appearance, and disabled body, Xi Jin fell silent.

Would this "fish" be easy to care for?

Ilya was a disabled mermaid, her tail covered in ugly black spots. On the verge of death, she was rescued by a beautiful, gentle caretaker, and from then on began a happy new life.

"Xi Jin, I want to eat fish."

"Sure, I bought some. I'll slice it for you."

"Xi Jin, I want to go out and play."

"Sure, I'll carry you."

"Xi Jin... I want to have a baby with you."

"Sure... wait, what?"

Xi Jin: How did raising a fish turn into getting a wife?

In the eyes of others, Xi Jin is a scheming, sharp-tongued commander. In Ilya's eyes, she's a gentle caretaker who gives her happiness.

In the eyes of others, Ilya is an ugly, unusual disabled mermaid. In Xi Jin's eyes, she's forever a frail mermaid who needs her protection.

In short, these two have an eight-meter-thick rose-colored filter when it comes to each other, and they're completely unaware of it.
