ON HOLD blood runs black

when seven boys locked into a mansion discovered a threat among them, they had to deduce which one of them was a traitor

the doors were all locked, the windows were unable to be broken

and one of the boys had black blood

the boy had to fit into society for the longest time, but now they could reclaim their life with six sacrifices

the sacrifices of the six boys with him

his time had come, his choice was made

but some of the other boys were calculating enough, so it would be harder to pick the boys off one by one

the problem was;

no one knew who among them had the black blood

and time was running out, or the six innocent would meet their end
