Is there a school novel that tells the story of the female protagonist disguising herself as ugly after her rebirth?

"It's a novel that I like very much. I've read it many times and forgot the name. The main character is a very fat girl. I remember that in the first chapter, the main character was holding a magazine and admiring the models on it and envied their figures. At that time, she was in an alley. Then, a man ran over and a group of people chased after him. The man used the main character to block the shield. After that, the main character was killed. When she woke up, she found that her soul was attached to a woman's body. I think she's from the underworld. Then, she received a mission. The target is at an aristocratic college. A senior from the same organization dressed her up as an ugly person and went in…Then, I remember that the female protagonist was reborn into her twin sister (although the sister is very beautiful). It's because in the sister's diary, she wrote that she had a younger sister who was very fat and had the same name as the female protagonist. Later on, she found out that the person who killed her was the principal of that academy, who was also the father of 'them'. That's the specifics. It's detailed enough.
And my sister's surname seems to be Su.

😋I recommend "A Glance at the Genius Student Is Alluring" to you. This is a school novel about rebirth and the female protagonist playing the ugly role. After the female protagonist transmigrated and was reborn, she became the daughter of a famous family, but was considered an ugly monster. Through hard work, she not only became beautiful, but also won the heart of the study god. I recommend this book to you. I hope you like this fairy's recommendation. Muah ~😗
