Yah, read if you wanna know about it.
Well I'm not sure if agrees with me, but overall this is what the manga is about:

So it talks about a girl whose parents were killed when she was 3 by some evil organization, so the girl began to live with a family that had a son. So the girl wants to take revenge on the organization (her objective).

Well yesterday I was drawing the girl (sketchesss) and I decided she should have red short hair, if that's okay with you, , of course.
