Considering the artistry and intention, I would like to recommend the very famous Squid Game. Squid Game can be seen as a mystery thriller dark drama, and first of all, it shows traditional Korean play, so the great advantage is that you can feel Korean tradition and culture indirectly. However, it may be a little difficult to watch because it is cruel for people to die through traditional game. It also shows social problems, showing materialism in competing through huge amounts of prize money, and showing social problems through stories of people who participated in the game. And it also shows how people change their minds and betray through games, showing various aspects of people. Personally, I'd like to recommend a drama lovely runner. The chemistry between the male and female characters is the best and they are also good acting. Situations that happen in the timeslip, and it will be fun to find the hidden stories or situation in it.
