FL unaware of ML's feelings

Friends, I would like to watch a drama where FL is unaware of ML's feelings for her. Recently I saw few scenes from Haechi drama. I felt that FL is not able to understand ML's feelings. It is cute. And in "The Story of MingLan" ML tries hard to make FL understand his feelings. Even though she is smart in other things she is very innocent when it comes to love. So I want to know if there is any other drama with similar plot. I would also like if the FL is strong and smart in other things and when it comes to love she is innocent.

- Hajimete Koi wo Shita Hi ni Yomu Hanashi (she's so oblivious, that's funny)

and maybe : 

- Twenty again

- Cheese in the trap 

- Feel good to die

 Sudosaure:

- Hajimete Koi wo Shita Hi ni Yomu Hanashi (she's so oblivious, that's funny)

Hoping for this didn't disappointed :D

Too late to say I love you for a good stretch
