I’m as confused as you
I think it's the younger brother's dreams. what I know from reading comments and the story, the red backlight or background means it's a dream and normal lighting is real. The younger brother craves his brother's attention ( in a sexually way) and the older brother yearns for their parents attention and love. To recieve the said attention and love he looked after this younger brother who has insomnia ( he doesn't know it's because of him). After not taking the supplement his younger brother gave him ( did he?? Now iam confused. I think him waking up in the middle of his younger brother's shakalakas was not a dream. And no I don't wanna re read that shit) he knew everything? Me thinks it's before the younger brother arrived and the older brother went to a different country because of the trauma? And scene!
TBH I lost all my braincells (which is 3) from reading this and trying to figure out shit.
It all makes sense now, literally think so hard after reading the last chapter when the younger brother arrived to Korea thank you!
Ur welcome lol
someone please tell me, is it all just the older brother's delusion? so all this time the younger brother has not returned from abroad? I'm a bit confused ...
