Bear with me before firing up your defense because let me tell you one thing. This drama had the potential of becoming the next goblin but the writer decides to go and shit all over it.
You have an amazing cast, but even a talented actor like Taecyon can't save this disaster. The story starts with amazing potential, great characters and it is introduced in a beautiful way. But eventually they make it into a sappy melodrama with love triangles that make no sense and a plot that raises your expectations but then crashes you.
The main leads are the only thing barely watchable but it's still not worth wasting a day of my life (I'm so glad i didn'tbinge watch this).
The story flow is extremely erratic and they somehow destroy the whole plot on the pretext of building the climax. (There is no climax)

Will i watch it again? Hell no.
Will i recommend it to anyone? I'm going to antirecommend (;aggressively advice you not to watch it)

I feel so bad for Ok Taecyon for ruining days of his life shooting this nonsense...
