She could not look away, though, however much the sight of him made her heart ache.

Love that had so often made her heart ache almost to breaking point.

It's what we never had that most makes my heart ache.

It makes my heart ache yet to call to mind some of those days.

The thought of sitting across from her in a heavy silence made his heart ache.

So why in hell did shooting him down make my heart ache?

He smiled in a way that made her heart ache.

The light at the mouth of the tunnel made my heart ache.

She was certainly attractive, and seeing her made my heart ache just a little.
