I don't read the manga version, so I don't know if the movie version is rushing the plot or not. But overall... the story is just so-so. It's kinda like a fairy tale.. I'm kinda confuse because without strong reason and right after some coincidence meeting, suddenly an idol fall in love with the female lead and want her to be his girlfriend..despite the age gap and different background.

The fetish issue that being told in the synopsis about the male lead is only shown a bit in the beginning of story, but then he seems very normal after all.

The girl is too naive but she is still in the high school so it's pretty normal. The plot is just too ordinary like in many others romantic high school movie with triangle love, childhood friend, amusement park date, jealous scene due to a classic set up and artist scandal.

I'm not really impress with the acting as well, but both leads are good looking. The genre is not really rom-com, there is not much comedy.

The issue in the boyband is kinda interesting, but it just another side issue.
The piano story is very cliche. This drama lose its main focus.
By the way, the actor's manager is too damn old. They should choose another young energetic actor to play the role.

Well if you are expecting dreamy plot then this drama is right for you. It just doesn't really make sense to be happen in real life for me.
