Falling for Big Sis Is a Piece of Cake!

Looking for Stories Where the Male Lead Tries to Seduce the Female Lead, But She's Too Straightforward to Catch On

I want to read books similar to "Sweet! The Aloof Beauty Becomes the Everyone-Loves-Her Star of a Boy Group Survival Show." Please recommend one where the male lead seduces the female lead, but she is very straightforward and completely oblivious.
