I think you mean sociopath.
he fits more into the psychopath category. they’re often confused and people use the terms interchangeably, but they’re not the same. sociopaths aren’t meticulous planners like psychopaths are. miyako had an elaborate plan to trap tatsuki, and he only left things to be found when he wanted them to be found. additionally, psychopaths tend to hold good jobs bc they’re manipulative. on the other hand, sociopaths have a harder time maintaining steady jobs. hope this helps a bit! i just wrote basic traits that applied, but they’re both interesting disorders if you wanna read about them
No, he showed apathy and lack of emotion since birth ( https://www.psychologytoday.com/us/blog/wicked-deeds/201801/the-differences-between-psychopaths-and-sociopaths)
So I thought Miyako was a psychopath because he couldn't feel normal emotions but then he felt sth towards the CEO boy??
