I recommend "An Ugly Girl Never Worries About Getting Married: A Beautiful Woman with a Jade Face", an ancient romance novel. The female protagonist was the youngest junior sister of the Five Poison Sect. She was also the ugliest one. Because of the scars on her face, she had to wear half a mask to show others. In order to go up the mountain to find Eldest Brother, she had gone through countless hardships and finally found the legendary Eldest Brother. However, Eldest Brother did not seem to be the person they had mentioned. In this time-travel novel, the female protagonist constantly concealed her appearance for her mission. She repeatedly changed her appearance and added a half-mask. I hope you like this fairy's recommendation. Muah ~😗
