Plot/Story
As the story unravell, you would find plots that are somewhat different from what you normally see in a typical romance story. The very act of sacrifice for the one you love, was well delivered in this story. It would really move a stone cold heart-person to tears after reading the said story. This manga will find the popularity Suzuka have garnered before if Half & Half will be serialize into series.

Characters
Although the story only centers around the two characters present in the story, still, with just a oneshot story, you would say that a 100+ chaptered-story is already equivalent to this oneshot story. Details like personality, character, and even the background or past story of the characters were clearly explained, not to mention the individual feelings of each character. Although the way it was explained was not straight-forward like those other manga - which makes this unique in its own way.

Drawing Style
The drawing style will be consistent with the next manga created by the said author. But still, the artwork is clean and some were portrayed realistically. Still, if compared to the subsequent sereis created by the said author, there's some progress that needed. But story-wise, its already a great work.

Enjoyment
This can be considered as one of those good romance manga created. although in its entirety its already complete and satisfying, it will be more enjoyable if this will turn out into a series. But still, can't get enough of it.

Overall
A two thumbs up! If for a musical player they call it repertoire for the list of those musical pieces they play, then this manga should be included to to the repertoire of those romance-manga lover.
