A Defeated Witch Would Never Submit to a Valkyrie

Su Li dies of illness and is reborn as a female black cat belonging to the pretty girl next door. Don't let her weak, timid little kitten appearance fool you: she's incredibly capable! She can keep house, cook, livestream, write, draw, and play games, and she'll even cuddle up to comfort the girl next door when she's feeling sad. What's more, she can transform into an adorable cat-eared girl! Maybe it's because they've spent so much time together, but one day the girl next door confessed to me. But I'm a cat! Taking me in is fine, but dating? No thanks! The girl next door doesn't seem willing to take no for an answer, though. With a sly, teasing smile, she says, "Little Black, you don't get to decide that~" The girl next door's eyes are sparkling with hearts. This black-haired catgirl is in danger!
