Will doing a favor for a girl I like land me in the friend zone?

She's sick, but she told me that she has to come in to school tomorrow to get homework and stuff. I then offered to pick up the work for her and bring it to her house after school. She pretty much freaked out (in a good way) at how nice of a gesture this was and started hugging me and telling how great I was. I could tell it was genuine, she didn't just do all that so I'd do her more favors in the future to get hugs or whatever. Keep in mind, she didn't ask me, I offered because I wanted her to stay home and get better and stuff. So, will an offered favor bring me closer to a romantic relationship, or closer to the friend zone.
