Yeh Saali Aashiqui is the story of love gone wrong. Sahil Mehra (Vardhan Puri) falls head over heels in love with Mittee Deora (Shivaleeka Oberoi) when they first meet in their classroom. Their love story hits a roadblock when he sees her flirting with another boy in the class. But Sahil forgives her when she asks him to give her one chance.
One day, Mittee is caught copying in the examination hall and she feels, Sahil is responsible for her being caught. Hell hath no fury like a woman caught copying. She decides to teach Sahil a lesson. She accuses him of trying to rape her. Sahil is arrested but instead of being sent to prison, he is sent to a mental asylum as it is revealed that he had killed his own father in a fit of fury some years ago and so he is assumed to be of unsound mind. Sahil pleads innocence and maintains in court that Mittee is playing games with him but the court does not heed his pleas.
What happens thereafter? Is Sahil able to avenge his humiliation? Even as Sahil is in the mental asylum, Mittee hooks up with a rich boy, Anuj (Ruslaan Mumtaz). Also, Sahil's past catches up with him. What is that? Does Mittee marry Sahil or Anuj?
