It's an enjoyable school romance manga, with a decent pacing so far (Chapter 8). Story; The story is about Kaede and Sakura, who one day become step-siblings. On top of that, they are of the same age and are in the same class in highschool. This will of course lead to a lot of awkwardness between them as potential "forbidden" feelings arise between the two step-siblings. Characters; Characterwise it is nothing special. There is nearly no focus on side-characters yet, apart from accompanying the main characters in their lives. In their school lives, both characters are pretty normal, so none of them are total outcasts or super popular. Kaedehas a rather cold and blunt character, but has a kind side and cares about / looks after Sakura.
Sakura is the typical kind, caring girl. She gets easily flustered though.

So, overall it doesn't reinvent the wheel, but that isn't necessarily a bad thing. The characters are likeable, the story and pacing makes sense. Whether or not there will be an actual romance developing between them is yet to be seen, but in my opinion it's worth a shot if you like romance.
