Looking for a manga

I'm looking for a manga where the female protagonist rides a bus, goes into a tunnel, and has an accident. A fire breaks out in the tunnel and she dies and is born in a new world. Before she died, she called her mother to tell her that she loved her. She had problems with her mother as her mother compared her to a neighbor's daughter who is successful. This is all i remember, it was in the first chapter and i dont remember if she was reborn or she possesed someone else.... I cried so much Reading this chapter and im in the mood to cry. English is not my first language.
