It’s about a girl who goes back (Idk is she died o something) tho the past. She has 3 brothers that now dote on her but before returning they doted on the other sister ( but she was a fake and when the family went broke she left) it’s in a school setting. And I remember the fl was in a mental hospital at the start(? Not sure.
Please help ┗( T﹏T )┛
