both about school and both has jang dong yoon, but both of them are really great, though solomon's penjury has darker tone

both are about fraud who become mr righteous by helping people in need, but Chief Kim is funnier

while the IB has the male lead as the introvert character, HTH has the female lead as the introvert character, overall they're both good series

korean version of hana kimi, but the comedy is not as much as hana kimi
