How to only rotate an object with mouse dragging in the clock wise direction?

I'm developing a game in which the user has to drag an object with the mouse, but I only want the object to rotate if the user drags it in a clock wise direction. This is my code so far:

     private void OnMouseDown()
     {
         isRotating = true;
         dir = Input.mousePosition - Camera.main.WorldToScreenPoint(transform.position);
         angle = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
         
         qStart = Quaternion.Inverse(Quaternion.AngleAxis(angle, Vector3.down)) * transform.rotation;
     }
 
     private void OnMouseDrag()
     {
 
         dir = Input.mousePosition - Camera.main.WorldToScreenPoint(transform.position);
         angle = Mathf.Atan2(dir.y, dir.x) * Mathf.Rad2Deg;
         if (angle-1 == )
         transform.rotation = Quaternion.AngleAxis(angle, Vector3.down) * qStart;
     }
 
     void OnMouseUp()
     {
         isRotating = false;
     }

Any help would be apreciated, thank you.
