Gameko no Chouhoroku

Her parents moved away, but she wanted to stay with the guy she likes, Naruse, so she takes the train to get to her school everyday. But it isn't cheap, so she decides to earn all her money by doing anything she can to earn it from her classmates and she is therefor nicknamed Stingy girl. From showing homework, to doing back massages, she does what she can. No one knows about this, of course, and she plans to keep it that way. Although this was how it was suppose to go down, not everything goes just how she wanted it to go.
