I accidentally watched this drama without any expectation, but later on, this drama turns out to be so good, romantic, touching, and amazing. The ML really did a great job for his acting skills and never think that this is his first drama as a main role. I guess, he will become more popular after this, cause he really deserve it! (not to forget, he is very handsome and charming) Especially, when he become blind, it's really touching. And for the FL, she's got so many drama before, so no wonder her acting skills also good.

First, the story is so beautiful, not like your typical C-drama. FL had a crush with ML and yes, she was the first one to take action and also she is the one who said she like him first. I love the character of FL that never give up towards the ML and always trying to understand him and make his life change to become colorful and happy. She also love him unconditionally and it really a touching and I also agree with the FL, when she said the ML eyes is so beautiful. Although, the ML's eyes is visually impaired or kind a blind, she always love him.

This drama really makes us realize that we should be grateful as long as we have eyes to see, ears to hear, nose to breath, and lips to speak, which is something that not everyone have it. And for the OST, omg I really love almost all the songs, it's really good...

Spoiler ;
I've read some comments that some people prefer that the story is better if ML's eyes isn't cure at all. I kind of disagree with it cause I really think that he needs to see the world if he could or giving that opportunity. He also need it cause he want to prove the FL's mom that he is not a burden for her and want to protect the FL as well cause he really loves her.
