Other people have thought that Clara and the Doctor are just friends.

Well, I think not.

For instance, the way he looks at her in some of the episodes, just screams love. Oh, and might I point out, the time when sinigang asked her to marry him? Did you see the Doctor's face? For a second, he looked scared/shocked. When sinigang said, you're smart, you're beautiful, and I've never met anyone like you, the Doctor nods his head, seemingly agrees! And the Doctor finally cuts in and tells Clara that he has some advice, but Clara tells him to be quiet. The Doctor seems to sigh with relief when Clara...

I don’t know where I am. I just know I’m running. Sometimes it’s like I’ve lived a thousand lives in a thousand places. I’m born, I live, I die. And always, there’s the Doctor. Always, I’m running to save the Doctor, again, and again, and again. And he hardly ever hears me. But I’ve always been there.

Clara: Doctor?

The Doctor: Yes, what is it? What do you want?

Clara:
Right from the very beginning.

Clara: Sorry. But you’re about to make a very big mistake. Don’t steal that one, steal this one. The navigation system’s knackered, but you’ll have much madami fun

Clara: Right...
