I watched this drama in 2014, i was 12 years old so my definition of what it was romantic, what was not were really strange. Now rewatching this drama with 18 years old i can really see the problems and how toxic it is this relationship beteween the two characters.
The girl doesn"t have choices of her own, she depends of this guy that she is attracted for about 4 years, and to actually have a function brain, she constantly needs stalk him everywhere he goes and do things she doesn"t wanna do...Wtf is the point of this??? The guy constant say how dumb,stupid, ugly and obssesive you are, just why you keep fucking trying????!!!!!
Not only the girl, but the main guy is also a big jerk, who thinks he is better than everyone else just because he's smart and handsome....Congratulations you have a brain, now use it to have empathy with others.
I only recommend this drama, if you already watched when you were younger and dummy like myself, you can see how much the things changes.
