Let me first explain how I got to watching this drama. I was going on a trip so I filled up on random dramas in case I got bored on the trip, among those dramas was this drama Stairway to Heaven, which I had heard so much about. So the trip comes and goes and one night I end up without internet, unable to sleep, and so I start watching this. In hindsight, I'm both glad and sad to have made that choice. Now onto the review: Story: 11/10 (because 10/10 is just not enough!): The story is very unique for me (maybe because this was my first drama of this genre). You end up hating the stepmother/stepsister so much that you want to jump into their world, and stab both...repeatedly. What else can I say? Oh right, keep a box of tissues handy otherwise you'll be wiping away your tears using your blanket(true story!) One other thing I enjoyed about this drama is seeing how the main male lead and the secondary male lead work together to accomplish a goal greater than either of them. Acting/Cast: 10/10 . Everyone in this cast from the child actors from the first few episodes to the adult actors were PERFECT. I had one small dislike in the middle of the drama, and that was how the main female lead cried. Yes. That's all. Later on, I got used to it and it didn't bother me at all, so it was just me. Music 9/10: I'm actually listening to the OST as im writing this review. It's GREAT, but not a 10. It conveyed the emotion perfectly and all that, so it was good for the drama...but for some reason giving it a 10 would be unfair in my humble opinion. Rewatch Value: 5/10: I DON'T rewatch dramas or movies 99% of the time which is why I gave it this low of a score. Overall: 10/10 - This is a masterpiece that every Kdrama fan should watch. But keep in mind, this can cause tears even from the eyes of manly men like myself. However, sometimes while those tears are dropping, your mouth will be smiling uncontrollably.
