I think it's a one-shot but maybe not. So, there was this girl and she helps classmates by giving them her notes for class or something and in exchange, she gets money. But she needs the money so she can go to school by train cause her house is really faraway. But then her classmates thinks she is using the money for other stuff and so i think they start ignoring her. So she decides to just go another school, but her classmates stopped her and told her they misunderstood. And in the end they made a donation thingy to help pay for the train.

Thank you to anyone who finds this.
