This show started strong in the first episode and the second gave a glimpse of what could be an outstanding show. But the writers missed it.
While Sea was really good acting a nearly blind person, he was not so great with the fluffy moments. Jimmy did grow in his acting but he could only do as much as he was given from the script.
The problem is the writing, the 180 turn from "enemies" to "lovers" was much too fast, the character development did just happen over night. Mhok should have much more struggle with his trauma and a spoiled brat does not turn 180° overnight also.
The side characters all did a good job
Production value and music was very good, but that does not help with the storytelling. The last two episodes are strange and the "happy ending" was too much. Day should have stayed blind, they should not have seperated in that way they did because Day was back to his spoiled brat days only thinking about himself.
The premise of the show was very good but they butchered it for "fan service" to make the show fluffy.
It's still enjoyable to watch when you don't expect exceptional story-telling.
