-Coming of the age drama of teenagers in high-schools
-Female Leads in both the series are pressured into do things and having to excel at it, like be the top student in school (in Student A) or play the piano (in Everything and Nothing) by their mothers and are sick of it.

Additionally both dramas showcase lavish sets and beautiful costumes.

I think this is the first show that has a very similar vibe to weight lifting fairy. The interaction between the two leads are so similar, the gestures and how they talk. Bring it on ghost has the supernatural aspect but overall if you want cute and flirty interactions like in weightlifting fairy watch bring it on ghost and vice veraa.

They are both slightly camp, truly silly, somewhat bonkers and absolutely marvelous in their own way. If you’re not into series like this you will find them both excruciatingly bad and not worth your time. But if you liked the one, please try the other!

Both are a decetcive historical type of drama and both include strong bromance so if you like bromance dramas with detective plot don't hesitate to watch them both.

"Am I the Only One with Butterflies?" has a 2nd season aswell!
(i'm optimistic that we'lll get a 3rd one too!)

Both dramas feature a psychopath who tried to pursue a life that others may deem to not suit them due to the fact that they had an inability to feel any emotions or emphatize with other people.

Both dramas had the presumed psychopath character trying their best to break away from the stigma people had of psychopaths in general as they try to lead a normal life.

Both stories are about the desperate lengths a parent goes to while looking for their missing son.
