I think after all maybe there's a reason why Jaekyung has such a bad personality and temper, maybe something from his past made him such a dick to everyone around him to Doc. Dan, I mean he showed in some past chapters signs of kindness especially his visit to the Grandma, I think deep down his not a bad person and maybe the author will show us a glimpse of his past, as readers we don't know anything about him after all. ( please don't get at me saying I'm defending him and that there is no reason that makes him treat Dan that way....I just shared my thoughts.)
