Thank you very much for your help, Nagoyankee :]
And as for "自分残せないかな", this was said after the main character tries to leave a handprint on the chalkboard of the music room. I got the sense that she wished to be able to leave some of herself behind in the room or something like that.

The whole food thing was a result of misreading だべ　as たべ and then assuming たべ was a shortened form for food since they were talking about food >.< A stupid mistake on my part >.<

Thank you very much again :] Your help was much appreciated.
