Cinderella's Tears the Stars Know My Heart

An accident made her an orphan. They knew each other since childhood, but for the sake of future development, they went their separate ways. Now that he has returned from his studies, he just wants to find her. Her cousin fell in love with him at first sight, so she would snatch her "things" at all costs, and even make her disappear forever. I don't know how to introduce it, I'm still working hard to write more.
