Both focus on school for delinquents, and a “masked” savior
Both are comical and looks like a comic in the exaggerated sense
Fls are both teachers, but instead of enemies, she and the ml are on the same side in study group

Both have the same heavily aesthetic vibes, and both “break away” from the usual kdrama mold of the cliche set most kdramas have so they’re unpredictable and fresh

The comedy vibes of both feel similar, both also have a bit of a unique little friendship and teaming

Both plots are about a guy that can suddenly understand animals and it becomes a funny cute dynamic

Both dramas revolve around animals and the main lead that can communicate with them to solve crimes
And both are comedies

Both female leads seem feisty even though they’re so adorably tiny, and both male leads are extremely hot

They’re basically twins, I mean if you like one you’d like the other
Same “evil” fl who seeks justice in an “evil” way of making the criminals see their wrongdoings
