Finding a manga

I need help finding out the name of this manga. The premise was that the MC died, and she reincarnated into another body. Nobody believes she was the girl that died, and her previous boyfriend doesn’t believe it either. The boyfriend turn kind of like a “bad boy” (hate that term but don’t know what else to call it). This manga was made before (?) the typical reincarnation type mangas.

I remember she also was somewhat pretty before she died, and now that she’s in a new body, she gets bullied by her classmates. I think she had curly hair in the new body but I could be wrong. And before she switched bodies, she talked to angels or something, and that allowed her to transport into another body.
