Line walker has more comedy, but both dramas are just as intense and action-packed. If you like spy dramas, with interesting characters and have great pacing/storyline. I recommend both of these dramas. Michael Miu is amazing in both.
Another best friends storyline focused on the main male leads and how they choose different paths in life, leading to different outcomes. Action & really well-written characters are in both these dramas, as well as a good amount of romance!
