I think the portrayal of Ryu Shi Oh's character is gruesome. The boy was an orphan, he had a traumatic childhood, his only friend gave him a gun and said "if I don't have to kill you, kill yourself", the girl he liked turned out to be the person he wanted to kill, the mafia put pressure on him, he had no patterns that he could follow. In my opinion, this drug shows that he no longer wants to be pushed around, he wants to be at the top of the food chain and decide his own fate. I was hoping that maybe they would at least throw him into prison and that he would be under the care of a psychiatrist - but apparently in vain. I'm so sadddd
