I don't actually know if this manga ends on chapter 10. But if that's the case, it's a shame. The story is actually pretty enjoyable and it has a nice flow to it. Direct to the point and with a nice ending as well. The split-personalities are pretty well developed, but, I wish they'd show us more of the past of Yamase, so we can know more about why the original personality wanted to dissapear in the first place. But yeah, pretty nice chemistry between the main characters, bland but kind of necessary side-ones and with just the right amount of comedy, drama and romantic scenes. Overall, for whatit is, it's a very well constructed story.
