Incisive Great Teacher (2014)

Both are about teaching and disciplining students/young men in an academy during the historical period and have romance involved (more bromance in Hwarang).

Both dramas have female lead as teacher in the ancient academy, see how they manage the naughty students and how interesting they handle the lessons. Both have romance involved, also bickering otp at first. There are also cute supporting characters inside.

Both have the same couple as the main actors, the chemistry is on point bc they are married in real life, Incisive Great Teacher is way more lighthearted and funny though

same vibe with an academy full of students, there's martial arts, comedy, good acting, romance and both are entertaining

Wallace and Liu Shi Shi are both in this drama, plot wise it's similar due to the group dynamic. Lots of friendship, adventure and martial arts themes

Consists of similar comedy styles between the two dramas and bickering otp becoming lovers storyline.
