LL and CC books about a beauty/geek girl

I want to look for LL and CC books about a beauty/geek girl. It’s basically a girl who is beautiful and popular outside of her house like at school mostly but becomes a nerdy geek at home which is her true self and no one knows her nerdy geek side. It’s like the webtoon True Beauty and the manga series Switch Girl. So if anyone knows anything similar in Episode, that would be great.
