So, what makes me remember this drama isn't really the story, but the music/OST and the casts' visuals.
I thought I had reviewed this when I watched it earlier this year, but now when I discovered I hadn't, I found I don't actually remember that much from the story, just the main essence.
I do remember the rather extravagant wardrobes, and the "too perfect" visual appearances.

It wasn't a waste of time watching this, but I won't re-watch it unless I am desperate either.
