Please recommend a few novels with a female protagonist who traveled through time?

Requirements: 1. Completed, at least almost completed.
2. The female lead should have a personality, not a noob.
3. There can only be one male lead, and he is very powerful. The female protagonist could only love the male protagonist. She could have a male supporting role, but she could not have any feelings or actions that exceeded friendship with him.
4. It would be best if they traveled to another time and space. Even in ancient times, they could not be involved with famous people. They did not want anything from Emperor Wu of the Han Dynasty or Emperor Taizong of the Tang Dynasty. They definitely did not want anything that was pure.
5. The ending must be happy.
That's all for now. The points may not be much, and the requirements are too much, but please help me. I'm eternally grateful.
I was a little depressed after watching 'A Phoenix Comes to Court'. It seemed to meet my requirements, but I'm a little naive and only know how to judge the male lead based on my feelings. I always thought that the male lead was Long Chengqian, but later I found out that it wasn't. I'm very depressed. And it seems that the female protagonist has a relationship with every male protagonist or supporting male protagonist. What I want is for the female protagonist to only like the male protagonist's novels, or for the female protagonist to not like anyone at first, but then she likes the male protagonist's novels. So please introduce those articles that can distinguish the male and female protagonists at a glance. Don't let the female protagonist struggle between a few men, which makes me very conflicted. I don't like such novels.

Answer 1

I recommend the following novels about the female protagonist's transmigration:
1. "The Interstellar Recipe of the Primeval Big Boss": The story of the female protagonist, a modern otaku, who transmigrated to the Interstellar Era and became a peerless prodigy to fight against evil.
2. "Finding the Master of Esper Abilities": The female protagonist transmigrated to another world, possessed divine artifacts and supernatural powers, and embarked on the path of supremacy.
3. [The Supreme God of War: The female protagonist transmigrated into the body of the useless Feng Lige. The female disguised herself as a man and walked step by step on the path of the Supreme.]
4. "The Supporting Female Lead's Lord's Visage": The story of the female lead transmigrating into a vicious supporting female lead, possessing healing powers, and fighting together with her comrades.
I hope you like my recommendation. Muah ~
