Pretty solid writing on the plot, but weak writing with the way they handle the characters and their relationships. It's like they hung a few personality and character traits and let it carry the whole 8 episodes. Like okay, Woojin is a cheap Marine nerd and Gun-woo is your typical hero MC who's poor with a heart of gold. No other background to Woojin whatsoever even if he's supposed to be one of the two main characters. Their friendship is very steady and was never put to the test. The pace is terrific for me to keep watching despite having pretty weak character writing or development. I did not cry when anyone died except Dokyeon (?), who locked his wife in the room and was expecting a son in two months. Myeon-gil is one of the biggest bastards I've seen in any drama ever. Ugh.
