Byeon Woo-seok carried the whole series, the rest of the casts are pure 💩 the storyline was interesting. The female lead character was supposed to be in her 30s who was there to find the solutions but the plot made her look like just an annoying teenage girl. I've never skipped this much before. If it wasn't for Byeon Woo-seok, I would stop watching at ep.3.
