Yeah ! It's definitely what I thought ! you didn't ask for it and you probably don't care but here's my hypothesizes as to why he could be autistic :') =
He looks like he has social communication and social interaction deficits, like, he has difficulties to adjust his behaviors to social contexts, for example, when he says blatantly his thoughts or have some behaviors without realizing that it could be seen as inappropriate, offensive or disrespecting but for him it's normal that's why he doesn't realize it. Also, it looks like he's has repetitive and restricted interests and behaviors, for example, he has the same routine everyday and he's really meticulous about the hours, like every mornings he has to do the same things at an exact hour. Also he looked really upset just for a seat, even though he explained why, it's really just a seat, there is no need to be this upset, but even if it can be futile for some people, this tiny thing can break his routine but mostly his peace. He may also have a deficit in non-verbal behaviors because he doesn't have a lot of facial expressions but he could also simply be a "dandere" which is just a anime/manga's character's type of personality lol. I hope the author will be more clear about it ! Anyway, I really love Sangwoo ! ٩(๑❛ᴗ❛๑)۶
ikr !!! it'd be a shame if the author doesn't explicitly say that he's autistic and makes it looks like he's just eccentric and some of his behaviors are just to be funny. I mean, at this point it's just so obvious but I'm a psycho-student, that's why it was obvious for me, I doubt that anyone would have realized that he might be autistic (except a few people, like you !). I think it would be super great and original to have a love story with an autistic person, also it would open people's minds about autism because many people have prejudices or a really limited representation/conception ! ٩(๑❛ᴗ❛๑)۶
does sangwoo have autism? it feels like it, and i fuckin love unbothered uke like him, it's refreshing
