So i read the manga 'I am here' and i liked the plot but i didn't like the main female lead much :/ I found her weak and cheesy .-. I'm looking for a manga with a plot similar to 'I am here' or a manga where the main female lead is a loner or has only 1-2 friends and struggles about not being noticed. But she can't be whiny,weak,cheesy or cliche.I'd love it if she's unorthodox :3 .I want her to have practical thoughts.Romance is optional.
No yaoi or shounen ai please.

Hwang Mi Ri kind of has stuff like that. (But nearly all her stuff are identical. You've read one, you've read all.) Of her works, Hot-Blooded Woman is the one that comes closest to what you're looking for, maybe.
