The usual makjang route without anything new or interesting that would stand out. Which would be fine if it weren't 160 episodes. Aside from the repetitive nature of the genre, they were including a lot of necessary fillers that were meaningless. Apparently the writer was struggling too, especially with the autistic main lead Hyung Woo. He was introduced briefly and had some screen-time in the first 30 episodes then he almost was never on screen other than once every 5 episodes until they brought him back for the last 30 episodes. I guess writing for an autistic character would require more effort.
