Sweet teeth is more sweet and cute.
Both dramas got very good chemistry between all pairs in drama.

Both tries to be funny romance in historical setting.
Both got scholar guy vs martial girl

24eps about 9 mins per one if you get rid of opening and ending songs you get 5min watchtime per ep.
In such short time they managed to cook interesting story with good acting.

Same male actor through by few years younger since its from 2013.
Same style of movie COPS, Criminals vs main hero.
