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
What if Jaeha is the true mastermind?
