For people like me who had no idea wth that ment :
Haphephobia is the fear of being touched. For some people, the fear is specific to being touched by people of one gender. For others, the fear extends to all people. People with haphephobia often experience physical symptoms of intense distress when they are touched.
I believe what Naeyoung is suffering from isn't Mysophobia, but rather Haphephobia - cause he usually flinches at human touch specifically, the rest everything (e.g. his patients) is fine for him. Naeyoung claiming that it's mysophobia a few chapters ago is just him trying to throw Jin off his case (probably).
