I really like this. It's got good flow and a very satisfying way to "overpower" the mc.I also like the concept that the mc can't just be a mere vengeful tool for his sister and actually has to have some character development although imo this development is not ideal, rather a bit confusing, -i dont know what the mc actually wants to do- but also not done yet i'm waiting to see where this all goes. I 'm waiting for next part!!!
