半分の月がのぼる空 (Hanbun no Tsuki ga Noboru Sora)

Plot Summary: During the winter, Yuichi was hospitalized due to hepatitis. Randomly he would try to escape from the hospital but would get beat up by the nurse. One day, he happened to meet Rika, a girl of his age, in the next building. He was fascinated by her beauty, but she was very selfish girl. Although she led him by the nose, he began to be attracted by her. However, when Rika told him about her illness, he knew why she acted so selfish; she didn't have long to live.

My Verdict: Considering the length of the anime, it's incredible that they've stuffed such a good story into only six episodes. Definitely 5 out of 5! Heck, there's even a live-action drama based on this anime! Available for DDL here.

Absolutely love these two lines from the anime:
命のかけて、君のものになる．
Inochi no kakete, kimi no mono ni naru.
At the risk of my life, I will be yours.

一番大切は何？自分の幸せ？それとも大切な人の幸せ？
Ichiban taisetsu wa nani? Jibun no shiawase? Soretomo taisetsu na hito no shiawase?
What's the most important thing? Your own happiness? Or your most important person's happiness?
