Where the heroine is bullied but her friend is popular and hangs out with her bullies

[Intisaar]

Does anyone know the name of this book where the heroine is bullied but her best friend, who's a boy, is popular? He ended up dating one of her tormentors. She's awful but the hero doesn't know that. He just assumed that the heroine refused to hang out with his friend and girlfriend because she's shy or anti social or something like that. There's a also a supernatural element to this story because the heroine kept talking to her future self in a mirror. If anyone know the title of this story, please let me know. Would really appreciate it
