National holidays and common celebrations, what is the most romantic gesture you've witnessed?

My cousin's kidneys had collapsed and he's been on the transplant list ever since.When his wife went for compatibility tests the first week of February she decided to gift him on hers.They were admitted to get ready for the surgery.It was decided that this had to happen on February 14th of last year.After the surgery was done, it was confirmed that the surgery was a success.It's a great way to express your love for another.Wishing them a long life.
