Can you recommend a love story where a woman disguises as a man?

I want to read this novel again, but I forgot its name…
If anyone knows, please tell me the name of this novel.
Story content:
The female lead's family was one of the Four Great Nobles, and their family owned a gem shop. Because he was framed by one of the four noble families (not just the four noble families, but the father of the male protagonist), his parents died and the gem shop closed. The heroine had forgotten everything because of the shock. With the help of the heroine's father's good friend, she was sent to an orphanage and secretly protected the heroine. Many years later, the female lead appeared in a male outfit. The female lead was entrusted with a mission by a rich man to obtain a gemstone. The condition was to obtain news of her parents. This was because the female lead had been doing missions to find information about her parents. The gem was with the male protagonist's father. The female protagonist went to the male protagonist's school in order to get the gem. She had all kinds of ways to get close to the male protagonist.
The female lead's surname was Tang, and the female lead's original name was Tang Xyun (I forgot the middle name). The female lead's father's friend helped her give her the name Tang Xyun in order to protect her. In order to get close to the male lead, the female lead used various methods to join the male lead's band as the lead singer. She even participated in the band competition. The female lead was proficient in various instruments. The female lead had a friend who was also in a band. The name of the band seemed to be "Lie". In the end, it was said that the gem was the heroine's family heirloom. The hero's father framed them in order to get it. In the end, the hero's father was caught. The male and female lead had known each other since they were young. The female lead rode a motorcycle all day. The female lead was very handsome. She had once wondered if she should have something that a girl should have. The male lead's character was very naive and easily trusted others. It was very scary when he was irritated. He liked the female lead since he was young, and even gave her a necklace when he was young (I forgot what the male lead gave the female lead when he was young, I think it was a necklace?), The female lead hung the necklace on her body. Once, she accidentally dropped it and was picked up by the male lead. The male lead then knew the identity of the female lead. The male protagonist's friend was the son of one of the four nobles. At first, he was very suspicious of the female protagonist, thinking that the female protagonist had a purpose for getting close to the male protagonist. At first, the female lead wanted to join the male lead's band, and the lead singer of the male lead's band had left. She was in a hurry to find someone to join, so she deliberately sang in the music room where the male lead passed by. The male lead heard the female lead's singing and wanted to pull the female lead into the band, but he was stopped by the male lead's friend because he felt that it was a little suspicious. Later on, the female lead acted in a scene where the male lead and his friend were on their way home, fighting with someone and then being chased. She deliberately wanted the male lead's friend to use this to threaten her into joining the band.
"The sequence of the story is different from the original, I'm jumping around."

Answer 1

😋I recommend "A Phoenix in the World Is Not to Be Trifled With" to you. This is an ancient romance novel written by the author, Chi Yan. In the story, the female protagonist, Helian Yue, transmigrated to a woman disguised as a man and ended up being pestered by The Preceptor. What was even more unfortunate was that he was her brother. The plot was getting better and better, and it made people's blood boil. They looked forward to seeing if she, who was disguised as a man, could resolve the awkwardness of her identity as soon as possible. I hope you like this fairy's recommendation. Muah ~😗
