Similar situation where the protagonist has just lost her mother and thought they had nowhere else to go. however, they had a grandfather who were willing to take them in but the other family members hated their mother and were against it.
Both the protagonist always smiled through tough times and were optimistic around their friends to not worry them.
Fruit basket has super natural and the similarity is but something smal.
