Due to an interesting start, including a character with selective mutism and the phone call plot in general, I was very hooked up until about the 4th episode. Then it starts getting BORING. The initial plot loses itself. From renting an amusement park, to falling off a cliff to evil twin brothers - this show includes every kdrama aspect ever used. I'm so disappointed, as now it feels I've been waisting my time on a show with bad writing. I will be finishing it, but only because I watched so far.
