Uke's a novelist and is narcoleptic (person with neurological disorder where a person suddenly sleeps any time of the day and eventually enters the stage 3 of sleeping called REM where you see dreams) p.s not an expert but that's what I've read in google.
He can also see uhmm dangerous places? And can see fairies? or mists which gives him warnings if any unfortunate events which are yet to occur.
Seme's a CEO of a company ( It's not in the story but I think they produce books and manhwas idk just guessing lol.) HE FREAKIN KNOWS HOW TO COOK WHICH IS LOVELY! And his feature and handsomeness is same as the person who has a "Mutual Understanding" or "Some Relationship" in Uke's dream. Love how they converse for the first time though anyways they are neighbors. And I LOVE THE PLOT CAUSE I LOVE NEUROLOGICAL DISORDER CASES AND PSYCHOLOGICAL CASES WHICH AFFECT THE BEHAVIOR OF PEOPLE TRAUMAS AND MANY MOREEE WHICH RELATES TO THE BRAIN AND EMOTION. Anywayss SO FREAKIN GOODD I'VE ALSO BEEN MOTIVATED TO LIVEE
