Before anything, this manga has the most epic "typical-feelings-declaration-interruption" of all time, I was expecting an "interruption" but how I laughed when I saw how the interruption was done, just brilliant xD.
Besides that, it has the same developments as any other shoujo, idiot male MC taking bad decisions, even if those decisions you can understand why he took them and an idiot female MC who was taking good decisions until the idiocy of the male MC brought down her emotional endurance. At least, in this manga, you can't bring yourself to despise any of them, even if you know what they are doing is stupid (beginning first with the male MC), it doesn't go beyond the "from here, I hate them now" limit.
Another plus, in Shoujo manga, normally it is the female MC who is stupidly annoying as hell, so she should be praised for not being that (much).
The only problem she has is that she cant sympathize at all with Takuma's sickness, she should be the first one to understand how serious it is, since she has been with him the most and seen how bad it is. With this I dont mean she should follow his every whim and idiotic decisions but, you'll understand what I mean when you get to the middle of the story. If you truly love someone and that someone is sick, you'll read, ask, get advice, visit doctors, learn whatever you may need to learn to support that person, she barely did anything regarding that, Takuma doesn't help either but... well. At least things do improve at the end, but that still annoyed me a little bit.
Scoring reasons:
+1: Epic "typical-feelings-declaration-interruption" moment x'D
+1: Understandable and barely likeable male MC, (you can't deny the issues he has)
+2: Acceptable story line, even if it was sometimes overly "shoujoesquely" dramatic.
+3: Really touching and tear jerking moments.
+3: Greatly likeable female MC.
-1: A lot of developments are unavoidable and predictable (except one), some stuff just have to happen. This minus also includes some other details that I didn't like but aren't that serious to depreciate this manga further.
