It's a short story. Aashi and Yuvaan had an arranged marriage but Aashi has loved him since two years. On the first night of their marriage he says that this marriage has no meaning for him and after that you can read in the story...

Bella Ross has always led a normal life, until three years ago the notes began. She knew he was there, hiding in the shadows but wouldn't show his face. She couldn't date or even talk to a man without his life being in danger and so she obeyed. She belonged to him. Her stalker. (Cover creds to @katrascal go check out their books!)
