I very much enjoyed this. It was super simple, but it didn't waste a single panel and it told a very unique story. A tragedy with some levity in the beginning. The image of the surgeon gently placing the heart-shaped cylinder into the heart-shaped thoracic* hole was genuinely funny. I don't know if the giant pile of hearts at the end is supposed to have a special meaning. I sorta got the impression that the donated love was flawed, but perhaps I'm reading too much into it.
*Note: Humans don't have thoraxes. Though we should.
