Seriously, I can't find anything it's so frustrating. All I want is this please help ???

I don't know of any dramas where a FL is explicitly bisexual or pansexual, but I can think of a few where the drama includes some queerbaiting scenes where the drama suggests that the FL likes another FL character, another FL character likes the FL, another female character flirts with the FL or makes her blush, or the FL thinks to herself for a moment that would kiss a certain girl despite the fact that she's a girl, or the FL and another FL character have a very close friendship where they joke about being each other's wives. 

I would also like to find such drama or movie. It would be even harder if you want only kdramas. All I saw is thís jdrama:
Boku wa Mari no Naka - It is a good drama, but the story is a bit complicated and psychological. 

Here is some list with bisexual and pansexual characters (MLs, FLs), maybe you will find something interesting there.
