As someone who's lost several relatives to cancer and know two people dealing with it right now, one with breast cancer, the other with terminal cancer... this really hits hard.
"In sickness and in health..." I wasn't expecting to get so emotional in a one-shot shorter than 40 pages, but WOW was that author able to pull everything together by the end (;w; ) the way the two of them tried looking out for each other in their own way, and in the end the husband was able to both love his wife and let her go :'O
