I think if you go into this drama with no expectations, it will surprise you. I have not read the manga, but I have watched other adaptations of this drama. And while I enjoy the Japanese remake better, this drama has a special place in my heart and has its own special aura.

The story is straight forward and somewhat cliche, and the acting isn't over the top or remarkable either, but there's a heart in this drama that will make you want to root for the girl. It's a perfect drama to watch as a teenager. I'd have to disagree with some reviews claiming that it showed Oh Hani, the main girl, as senseless. I think it actually depicted somewhat realistically just how swept up some teenagers can get in love interests, that it becomes the whole world to them, but they come to realize that adulthood has many aspects and finding romance is just one of them. Of course the cold male lead ridiculing the young girl is not something anyone wants to support, but this drama doesn't justify him being an asshole either. It instead does show character development and a budding romance between the two leads. I felt like the nearly robotic way the male lead portrayed himself in the beginning wasn't something that deviated out of character, and instead was portrayed fine.

One review said that the mom was helping Oh Hani stalk her own son: well they two leads are living in the same house, it's hard to be depicted as a stalker when you are residing in the same place in all honesty. The mom is actually one of the best reasons to watch this drama. She does want the two to get together because she's always longed for a daughter, but she isn't forceful and doesn't get in the way of the relationship either. It was refreshing to see a Kdrama mum be all over the female lead instead of being against her.

Overall this drama is worth dipping your toes into at least once. I found a special spark this drama had, if you don't feel it that's fine, but it definitely is worth looking into.
