The female lead in both the dramas suffer from inferiority complex about their appearance. The male lead falls first both in mask girl and true beauty:)

Some of its similarities according to me are:-
- First love
- High school to college
- Youth
- Popular Male lead
- Cute and fluffy

Both of the dramas are based on youth.
Here are some of the similarities i found:-
1- Both the leads couldn't stand each other at first but later on fell in love when they started interacting more.
2- The male lead in both the dramas is a genius.
3- Both the dramas follow their journey from high school to college and then finally both the leads recognised their feelings for each other.
4- Both the dramas are cute and fluffy.
