Was the heroine in the novel called the " ugly duckling "?

I recommend the following novel to you. I hope you like it. The first one was a fantasy romance novel,"Song of Cold Moon". The female protagonist was also known as the ugly duckling. She was transported to a magical world and became a student in an academy, beginning a journey of cultivation. The second book was a light novel,"The Ugly Duckling of the Net King's Former Home". The female protagonist, Ugly Duckling, had a cute and silly personality. She was a warm-hearted girl and was called Ugly Duckling by the male protagonist, Long Ma. I hope you like this fairy's recommendation. Muah ~😗
