I have very mix emotions about this. It could be consider really good and rare gem. Even I can see that.
But at the same time, I love the older brother, the MC appears like scum whose envious. I see a lot of Japanese Protagonist like this.
But I also like how MC was the first one to step in getting revenge for his Brother. Only time will tell if this is good or not. I'm really wondering why no one is translating this!
I wont judge this story yet. Too much we don't know!
