I've watched this multiple times and it still resonates every single time. The characters were so well thought out and developed beautifully along the end. Slice of life dramas don't usually discuss things like the actual isolation of being orphaned because most just choose to deal with them in a different angles. I feel like this kind of story-telling deserves more in terms of exploration and expansion. The world is full of adults who seem to have made it their jobs to displace youngsters out of the need to feel superior. That there can be people like Donghoon who could help put you into a map of friendships and help you find a place amidst strangers is comforting. The actors' portrayals of their roles and the way each character unfold into their own stories are all top-notch. Must-watch!
