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.)

It was a beautiful short manhwa both story and art why are people complaining in the comments? The author gave you a short story with a setup, confrontation, and resolution, gave you a brief idea about the main characters problems in life and how they ended up solving them and left the rest of the details to your imagination.
That small line on his upper lip bothers me a lot he would have been more handsome and his features would have been more attractive if the artist had given up drawing that line.
It's suppose to represent his lip like his cupids bow
