@Shellsea he doesn't notice that his older brother is treated that way because he hasn't been told. but people can be lonely in different senses too. while MC is lonely physically with no one, his younger brother (junwoo i think) is lonely surrounded by people who don't understand him nor do they want to.
@seasonally depressed pansexual as a middle child when my brother said you could never understand me I said bro atleast they are listening to you...he always had birthday parties and toys every year but i was using second hand things from literally hundred years ago and about birthday party, I never had one.....actually I read the whole thing and brother knew from the start...did you forget the dinner scene, anyways how we can see he is loved by his parents he could atleast voice up..I guess he doesn't have any ability or its just another plot hole, but you compare mc loneliness to brother's...mc is suffering from the childhood mentality, socially and physically..but hey its your opinion and I respect that hahaha and I also love pearl boy.
