i have to recheck and apparently the novel does expound on this.
misdiagnosis happens. all the things he does really screams autistic to me ngl. yeah he doesn't need to be labeled but it explains a lot of tendencies he has - sticking to routines, hyperfixation on special interests, issues with social cues, etc.
yea i get that too.
i think hes probably on the spectrum too but seeing as hes honestly doing fine in his life and jaeyoung is alright with it, hes chill, he dont need the doctors or whatever. i feel like itll kinda make everything more serious and like become a big part of the story if he gets a diagnosis, and itll make the whole theme change or something. i do agree with u tho about his symptoms

it's basically official that sangwoo is autistic isn't he? he finds it difficult to grasp the most basic social stuff - in this chapter for example he thinks going away = breaking up. he needs it to be spelled out for him.
