This is one of the most beautiful, pure, raw, and just amazing pieces of literature I've read! I loved everything about it! I wish they made it clear that she'd be alive for really long alongside him, AND that we had gotten to see them getting married. I wish it was a lot longer, but it was so fucking amazing and beautiful! It was brilliant! 10/10 (more like 100/10). I'll re-read this, most likely more than once!
