, I recommend the following novels to you. They are all one-on-one transmigration novels. The female protagonist has a cold personality: " Marquess's Life ": The female protagonist is a fake marquess, and the ending is one-on-one. This book was a little mind-boggling, but it was very exciting. [Poison Concubine Proud in the Sky]: The female lead is a descendant of a reclusive Blood Clan. Her personality is neither naive nor brainless. The ending is one-on-one. The male lead was also very powerful. The female lead was a good-for-nothing Third Miss, but she became very powerful and had a strong personality. The ending was one-on-one. " The Cold King as a Concubine ": The female protagonist has an independent personality, not Mary Sue. The ending is one-on-one. The male lead was a cold, heartless, and temperamental prince. I hope you like my recommendation.
