What if Jaeha is the true mastermind?
imagine this:
lonely child Jaeha suddenly acquires a sickly younger brother who has never known a true family (Yoseob). He pours his affection onto Yoseob but also tells him everyday "im the only one who cares about u. we only have each other. everyone else can go to hell." Angry at his former best friend for betraying him Jaeha feigns sickness after being soaked in the water former best friend poured on him. "its all his fault. u must avenge me, bc we r brothers" he tells Yoseob, and Yoseob believes him. He probably didnt instigate the Yura thing though
It's not your fault, Jaeha.
It's not your fault either, Taeoh
It was all a series of unfortunate events that caused all of this.
And it all started thanks to the parents that abused their only child.
it matters on how they raised Yoseob but a bit of it comes from his actions. He chose to kill those people on his own will. Still pity him like crazy, he just needed a hug and some therapy.
True.
