*sigh* What can I say that hasn't been said already? I cried a little, and now my eyes burn, it hurts. I added a tag that says "heartwarming", but I think that isn't quite right. This story fills your heart with sorrow, with happiness, with borrowed love, a little bit of darkness and a little bit of light. If, like myself, you open a lot of mangas to read them one by one all day long, make sure to put this one as the last of the day, 'cause it's gonna break and steal your heart and nothing else will feel quite enough after this.
