Raising Yao Si's Little Bun (Multiverse)

In her previous life, she spent her entire life as an assassin, giving her life to that "father" of hers. Before she died, she outsmarted him once, and at least went out on her own terms. She thought her life was over, but then she came to this world. Fortunately, she had her partner by her side and a perfect family. Her partner eventually found happiness, while she picked up an adorable little dumpling. His name was Miyazaki Yoji, but so what? As long as he didn't betray her, that was enough. She thought she was already happy enough, but who could have guessed that the little dumpling would have to return to his original world? It didn't matter, though. She gave up everything, even her identity as a human, in exchange for another chance to see him. This time, she absolutely would not let him go. But why does the grown-up little dumpling she searched so hard to find stare at her with eyes glowing an eerie green, like a wolf's? The protagonist is the receiving partner. If that's not your thing, please don't read. Theme:
