The names of the characters in the novel

I'm going to write a campus romance novel, but I don't know how to name the characters. The girl: Actually, the female lead had already gone. She was called " Lan Ruoxi," but she did not know if there was a better one. 14 years old, sometimes sunny and cheerful, sometimes lonely and calm, silent. An orphan abandoned by his parents since childhood. < Second Female Lead > was the best friend of the female lead. She was 14 years old and cheerful. Her family was originally very rich, but after their family went bankrupt, her father was so sad that he jumped off the building. Her mother also committed suicide because of her father's suicide. Therefore, she became an orphan and lived with the female lead. At night, she went to the night market with the female lead to sell things. The third female lead was a shy girl who kept a distance from the first female lead. The second male lead had pursued her before, but she liked another guy. Now that the second male lead didn't like her, she changed her mind and started pursuing the second male lead. The boy: [Male lead] and the female lead met on the bus. They were always very low-key and didn't like to talk at first. After meeting the female lead, they gradually became cheerful. He was very fair and handsome. He liked blue and always wore a blue jacket, a white T-shirt, and a couple's necklace. He had a couple necklace with the female lead. [Second Male Lead] The person that the female lead once had a crush on. Handsome, lively, cheerful, and a little narcissistic. Previously, he had pursued the third female lead. When he pursued the third female lead, the first female lead had a crush on him. However, he was careless and did not know at all. Instead, he became good friends with the first female lead. Now that he liked the female lead, he wanted to stay away from the third female lead and be in the same class as the female lead. [Help me come up with a few more names, thank you. The third female lead's name must have a purple character. Also, help me come up with a novel title related to the couple's necklaces. Thank you.] There were good ones. I'll give you extra points
