I think it reflects how he has spend his life between jobs and taking care of his grandma so he hasn't had any time to make meaningful connections with people, and I feel like he always treats people with distance, he's a good person, strikes a conversation but to a limit and doesn't engage. Remember he didn't grew up with parents so he doesn't like to express his feelings cuz I can bet he didn't want to worry his granny so he never learned how to.
Being a physical therapist and being a doctor are two different things.. besides.. you know there are people out there without friends & family? It’s not that unusual. Especially in a situation like Kim Dan. If you eat shit all your life and all you can do is concentrate about school and surviving you simply don’t have the strength and nerves for friendships. Especially if you got bullied your whole school life. All what we saw from Kim dans life made him the dude he is now. That’s his personality. It’s there, you just don’t like it because it’s „bland“ in your eyes.
He's not a doctor. He's a PT. And I agree with the other reply, it makes sense that he doesn't have friends if all he's even done is work and take care of grandma. Plus he always had those loan sharks around him before Jaekyung
Besides the glaring problems of this story what annoys me of webtoons is how insanely superficial they are in character writing, you just have pretty drawings and they become so incredibly popular.
How is grown adult kim dan who is a doctor and also a super nice person, have no other emotional support except his grandma? Not a single friend? It's so boring to read sometimes idk they couldn't bother with giving characters any more background and its just "these two characters are pretty and have sex until they dont"
That being said i'll keep reading because i still enjoy eating garbage
