Hi everyone,

I'm new to this site. Since I had seen the topic was "I'm looking for", can anyone recommend me a manga that has a female protagonist that has hidden potential. In a sense that she chooses to hide her true identity or form from others and secretly works out. Like she is literally day and night when it comes to how she looks. I am open to suggestions and also let me know if you want me to clarify or provide more detail.

Thanks!
