This is not actually a romcom, it's not very lighthearted or cute. Teen dramas tend to be dismissed easily as just that just bc of expectations. This is neither too dark or too light imo. The theme is rather universal, whether to stand up to fight injustice, or to go with the crowd which is always easier. Very few people can stand strongly behind what they see as right and ethical when the rest just have an easy time not caring. School bullying and burnout due to insane pressures and competition are also rather universal I guess, not only happening in SK. Also the rich/poor divide is strongly accentuated here. The romance thread is nicely executed. In good taste. This is far from a perfect k-drama but worth watching nevertheless.
