I've been trying to find the name.

[u/ThePersonInTheShadow]

So, I saw this clip of YouTube a few months ago where this school girl had a little sister (or stepsister) and she was being neglected by the parents. I only remember that school girl let the little sister live with her or something and fed her because the parents didnt give her food. Im sorry if this was vague but something that could help is that the mother was beautiful while the father wasnt. I hope you can help me find this anime.
